Answer:

[tex]B = 50.5^\circ[/tex]

Step-by-step explanation:

Given

[tex]AB = 11[/tex]

[tex]BC = 7[/tex]

See attachment

Required

Determine [tex]\angle ABC[/tex]

[tex]\angle ABC[/tex] implies that we calculate the angle at B.

Given that:

[tex]AB = 11[/tex] --- Hypotenuse

[tex]BC = 7[/tex] --- Adjacent of B

We apply cosine formula

[tex]\cos(B) = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos(B) = \frac{BC}{AB}[/tex]

[tex]\cos(B) = \frac{7}{11}[/tex]

[tex]\cos(B) = 0.6364[/tex]

Take arccos of both sides

[tex]B = cos^{-1}(0.6364)[/tex]

[tex]B = 50.5^\circ[/tex]

Answer:

11. 10x^2 - 13x - 3

12. 5x^2 + 18x + 5

Step-by-step explanation:

11. Product means multiplication, so you can multiply (5x + 1) and (2x - 3).

[tex](5x + 1) * (2x - 3)[/tex] - Using the FOIL (First+Outer+Inner+Last)

So: [tex](5x*2x) + (5x*-3) + (1*2x) + (1*-3)\\10x^{2} -15x + 2x -3\\10x^{2} -13x -3[/tex]

12. [tex]3x^{2} + 8x - 1 + 2(x^{2} +5x + 3)[/tex] (So, you distribute the 2 to x^2 + 5x + 30, then combine like terms).

[tex]3x^{2} + 8x - 1 + 2(x^{2} +5x + 3)\\3x^{2} + 8x - 1 + 2x^{2} +10x + 6\\(3x^{2} +2x^{2}) + (8x + 10x) + (-1+6)\\5x^{2} + 18x + 5[/tex]

Answer:

There is a 92°F difference between the two cities.

Step-by-step explanation:

Since you are finding the difference of temperatures between the two cities, you need to subtract -14 from 78. It looks like 78-(-14). Since you are subtracting a negative number, the equation becomes 78+14. 78+14 is 92.

Answer:

156.5

Step-by-step explanation:

The height of the flagpole to the nearest tenth of a foot is 156.5 ft.

Word Problems involving the use of the Pythagoras theorem need careful understanding to discern the complexity of the variables given, the using the Pythagoras theorem to solve the eqaution.

The Pythagoras Theorem states that the sum of the squares of the opposite side and the adjacent side is equal to the hypotenuse square.

From the information;

Using the Pythagoras theorem, we have;

hyp² =  opp² + adj²

350² = (2x)² + x²

350² = 4x² + x²

122500 = 5x²

x² = 122500/5

x² = 24500

x = √24500

x = 156.5 ft

Therefore, we can conclude that the height of the flagpole is approximately 156.5 ft.

Answer:

  (b)  x = 3, y = 2

Step-by-step explanation:

In order for the triangles to be congruent by the HL theorem, the hypotenuses must be congruent:

  3y = x+3

and the corresponding legs must be congruent:

  y +1 = x

__

We can solve this set of equations by substituting for x:

  3y = (y +1) +3

  2y = 4 . . . . . . . .subtract y

  y = 2 . . . . . . . . .divide by 2

  2+1 = x = 3 . . . substitute for y in the equation for x

The solution is (x, y) = (3, 2).

Answer:

15,840 i did this in test and got 100%

Step-by-step explanation:

The total feet ran by Rachel is given by the equation A = 15,840 feet

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the total miles ran by Rachel be A = 3 miles

Now , the value of 1 mile = 5,280 feet

Substituting the values in the equation , we get

The distance of 3 miles in feet = 3 x value of 1 mile

On simplifying the equation , we get

The distance of 3 miles in feet = 3 x 5,280

The distance of 3 miles in feet = 15,840 feet

Therefore , the distance ran by Rachel A = 15,840 feet

Hence , the equation is A = 15,840 feet
