Answer
m∠Y = 105 degrees
Step by step explanation
Here ΔABC and ΔXYZ are similar. Therefore, the angles of the two triangles are equal in measure.
m∠A = 44 = m∠X, m∠C = 31 = m∠Z
m∠Y = m∠B
m∠X + m∠Y +m∠Z = 180 {sum of the interior angles add upto 180]
44 + m∠Y + 31 = 180
75 + m∠Y = 180
m∠Y = 180 - 75
m∠Y = 105
Thank you.

Answer:
48
Step-by-step explanation:
Evaluate each of the functions by putting the number where x is.
Then the difference is ...
g(-7) -f(-7) = 45 -(-3) = 45 +3 = 48
Answer:
Step-by-step explanation:
4. h(x) = 2x^2 + 14x - 60
Step-by-step explanation:
Given that h(x) is a quadratic.
Also, h(3) = h(-10) = 0
(A) h(x) = x^2 - 13x - 30
=> h(3) = 3^2 - 13(3) - 30
=> h(3) = 9 - 39 - 30
=> h(3) = -30 - 30
=> h(3) = -60
=> h(3) ≠ 0
(B) h(x) = x^2 - 7x - 30
=> h(3) = 3^2 - 7(3) - 30
=> h(3) = 9 - 21 - 30
=> h(3) = -12 - 30
=> h(3) = -42
=> h(3) ≠ 0
(C) h(x) = 2x^2 + 26x - 60
=> h(3) = 2(3^2) + 26(3) - 60
=> h(3) = 2(9) + 78 - 60
=> h(3) = 18 + 78 - 60
=> h(3) = 96 - 60
=> h(3) = 36
=> h(3) ≠ 0
(D) h(x) = 2x^2 + 14x - 60
=> h(3) = 2(3^2) + 14(3) - 60
=> h(3) = 2(9) + 42 - 60
=> h(3) = 18 + 42 - 60
=> h(3) = 60 - 60
=> h(3) = 0
And
=> h(-10) = 2(-10)^2 + 14(-10) - 60
=> h(-10) = 2(100) - 140 - 60
=> h(-10) = 200 - 200
=> h(-10) = 0
Clearly we have,
=> h(3) = h(-10) = 0
Hence, the correct option is (D) h(x) = 2x^2 + 14x - 60
