Answer:
∠ A = 60°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°
------------------------------------------------
Using the cosine ratio in the right triangle
cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus
∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )
Find the value of x. Then find the measure of each angle.
Answer:
1)103
2)103
3)77
Step-by-step explanation:
(first, look at the photo)
x + (x - 26) = 180
2x - 26 = 180
2x = 206
x = 103
2.angle= 103
3.angle = 103 - 26 = 77
hope this helps ^-^

Divide the product of 6 and 5 by the quotient of 12 and 4
pls help! what is the expression??
Answer:
Let variable y be the unknown number. So triple a number means 3y. The difference (use minus symbol) of triple a number and 5 should be written as 3y −5.
Answer:
the product of 6 and 5 is 30. the quotient of 12 and 4 is 3. so, divide 30 by 3. your answer is 10!

7. We learned that in a plane, two lines perpendicular to the same line are parallel. Use the rectangular solid below to explain why the words "in a plane" are needed.
Answer:
"In a plane" imposes the condition that these 3 lines exist in ONLY 2 dimensions, otherwise, the statement, "Two lines perpendicular to the same line are parallel" is false.
Example 1: lines CE & DF are // & perpendicular to CD. TRUE
Example 2: lines CE & BD are // & perpendicular to CD. FALSE

12(x−13)=13(12−x) x=?
Answer:
x = 12.48
Step-by-step explanation:
Simplifying
12(x + -13) = 13(12 + -1x)
Reorder the terms:
12(-13 + x) = 13(12 + -1x)
(-13 * 12 + x * 12) = 13(12 + -1x)
(-156 + 12x) = 13(12 + -1x)
-156 + 12x = (12 * 13 + -1x * 13)
-156 + 12x = (156 + -13x)
Solving
-156 + 12x = 156 + -13x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '13x' to each side of the equation.
-156 + 12x + 13x = 156 + -13x + 13x
Combine like terms: 12x + 13x = 25x
-156 + 25x = 156 + -13x + 13x
Combine like terms: -13x + 13x = 0
-156 + 25x = 156 + 0
-156 + 25x = 156
Add '156' to each side of the equation.
-156 + 156 + 25x = 156 + 156
Combine like terms: -156 + 156 = 0
0 + 25x = 156 + 156
25x = 156 + 156
Combine like terms: 156 + 156 = 312
25x = 312
Divide each side by '25'.
x = 12.48
Simplifying
x = 12.48
Answer:
x=72±2180313=72±21803√13

Michael is using a number line to evaluate the expression –8 – 3.
A number line going from negative 12 to positive 12. A point is at negative 8.
After locating –8 on the number line, which step could Michael complete to evaluate the expression?
Michael could rewrite the expression as Negative 8 + 3 and move 3 spaces to the right.
Michael could rewrite the expression as Negative 8 + negative 3 and move 3 spaces to the right.
Michael could rewrite the expression as Negative 8 + 3 and move 3 spaces to the left.
Michael could rewrite the expression as Negative 8 + negative 3 and move 3 spaces to the left.
Answer:
Michael could rewrite the expression as Negative 8 + negative 3 and move 3 spaces to the leftStep-by-step explanation:
Given
Expression
-8 - 3Solving
-8 - 3 = (-8) + (-3) = - 11-11 is smaller than -8 and therefore is on the left from -11 by 3 spaces
Correct choice is:
Michael could rewrite the expression as Negative 8 + negative 3 and move 3 spaces to the leftAnswer:
Answer is D.
Step-by-step explanation: If you see all the answers, C. has no negative sign included into it, so its not C, and its not A or B because they move to the RIGHT side. Therefore, D is your answer.

Answer:
alternate exterior angles
can anyone plz answer this question now?
Answer:
58
Step-by-step explanation:
Step-by-step explanation:
AD=DC
So angle A is equal to angle C
Let Angle A be x
And angle ABD is equal to 90 degree
So in triangle ADB
90+32+x=180 (angle sum property)
x=180-122
x=58
As angle A and angle C are equal
So angle C=58 degrees
Hope it helps

the table models the linear relationship between the calories marcy burned and the time she spent on the bicycle. what is the rate of change of the calories marcy burned with respect to time
is the perimeter 70?
Answer:
Step-by-step explanation:
AC = 8 + 15 = 23
C to the tangent point of BC = 15 (tangents are equal when they come from the same point.
B to the tangent point of BC = 12 (same reason).
BC = 15 + 12 = 27
By a similar argument BA = 12 + 8 = 20
So add them together. 20 + 27 + 23 = 70 I think.
You are absolutely right. Or we both are wrong.

Lina and Josh each made a factor tree to find the prime factorization of 126. Lina's Solution Josh's Solution 2 factor trees. Alina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126 = 2 times 3 squared times 7. Josh's factor tree of 126. 126 branches to 2 and 63. 63 branches to 9 and 7. The equation is 126 = 2 times 7 times 9. Which statement explains the accuracy of the students' work? Lina's solution is correct because it expresses 126 as a product of prime factors. Josh's solution is correct because the factor tree of every even number must begin with 2 and its factor pair. Both solutions are correct because they both express 126 as a product of factors. Neither solution is correct because the factor tree should have begun with 6 and 21.
Answer:
Lina's solution is correct because it expresses 126 as a product of prime factors.
Step-by-step explanation:
Prime factorization can be defined as a methodology of breaking down an original number down into the set of prime numbers which when multiplied together give us the original number.
Prime factorization makes use of a factor tree
The number we are to carry out prime factorization on is 126
126
/\
3 42
/\
6 7
/\
2 3
The Prime Factorization is:
2 x 3 x 3 x 7
Hence, Lina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126
= 2 times 3 squared times 7.
Is correct.
