Answer:
1. The similar triangles are ΔXYZ and ΔPQR
The triangles are similar by the AA rule of similarity
2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles
3. x = 17.5
4. x = 20
Step-by-step explanation:
1. The angles of triangle ΔXYZ are;
∠X = 32°, ∠Y = 84° and ∠Z = 180° - (84° + 32°) = 64°
The angles of triangle ΔPQR are;
∠P = 64°, ∠R = 32° and ∠Q = 180° - (64° + 32°) = 84°
The angles of triangle ΔABC are;
∠A = 64°, ∠C = 92° and ∠B = 180 - (92 + 64) = 24°
Therefore, the two similar triangles are ΔXYZ and ΔPQR
The triangles are similar based on Angle-Angle (AA) rule of similarity
2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles
3. We have by corresponding triangles formed by the tree and Enzo as follows;
5 ft./(6 ft.)= x/(21 ft.)
∴ x = 21 ft.× (5 ft./6 ft.) = 17.5 ft.
x = 17.5 feet
4. By corresponding triangles, we have;
(35 ft.)/(40.5 ft.+ 54 ft.) = x ft./(54 ft.)
∴ x ft. = (54 ft.) × (35 ft.)/(40.5 ft.+ 54 ft.) = 54 ft. × (35 ft.)/(94.5 ft.) = 20 ft.
x ft. = 20 ft.
∴ x = 20

Answer:
The answer: ( 2 , -3 )
Step-by-step explanation:
equation (1): 5x + 2y = 4
equation (2): y = x - 5
step1: sub ( x-5 ) for y in equation 1:
5x + 2 ( x-5 ) = 4
step2: multiply 2 by the bracket:
5x + 2x - 10 =4
step3: add the x term together:
7x - 10 = 4
step4: add 10 for both sides:
7x = 14
step5: divide by 7 from both sides to get the value of x:
x = 2
step6: sub ( 2 ) for x in equation 2 :
y = x - 5
y = 2 - 5
step7: simplify to get the value of y:
y = -3
So the answer is:
x = 2 and y = -3

What is the area of the figure below?
Answers
Answer:
104
Explanation:
1. Split the figure by the line the larger portion creates.
2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.
3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.
4. Now, we simply do 6 · 8 = 48. Almost there!
5. Finally, add the values of the left side and the right side (48 + 56 = 104)
6. YOUR ANSWER IS 104 cm squared.

Answers
The another way is same as;
Multiplying by 0.5 with original price.
Here,
A shop owner increases some prices by 50%.
We have to find another method to find same condition.
What is the percentage?
A relative value indicating hundredth parts of any quantity is called the percentage.
Now,
A shop owner increases some prices by 50%.
Let the original price is x.
Then, The increase value = x * 50% = x * 50/100 = 0.5x
Hence, To find the increase value we have to multiply by 0.5 with original price.

Tom and Katie are discussing the sequence: 22, 17, 12, 7, 2
Tom says the nth term rule is: -5n+17
Katie says the nth term rule is: 27-5n
A)Only Tom is correct
B)Only Katie is correct
C)They both are correct
D)Neither are correct
Answers
Answer:
B
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 22 and d = - 5, then
[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B

Answer:
B
Step-by-step explanation:
It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.
