Y = x² + 2x – 45
y = -3x + 5
-3x + 5 = x² + 2x – 45
x² + 5x – 50 = 0
x has two values 5 and -10
x = 5 => y = -10
x = -10 => y = 35
Good luck.

Answer:
∠A = 94°
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180°.
Therefore, if ∠A and ∠B are supplementary:
⇒ ∠A + ∠B = 180
⇒ (2x + 10) + (2x + 2) = 180
⇒ 4x + 12 = 180
⇒ 4x = 168
⇒ x = 42
To find ∠A, substitute found value of x into the expression for ∠A:
⇒ ∠A = 2(42) + 10 = 94°
