Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18
So the first angle is 18° and the second is 72° (18*4)

Answer:
a-b = 5x² + 6x -8
Step-by-step explanation:
a = 3x² + 5 -6 ⇒ 3x² -1
b = -2x² -6x + 7
a-b
3x² -1 -( -2x² - 6x + 7)
3x² -1 + 2x² + 6x -7
5x² + 6x -8
The answer 45 and the other one to the question is invalid
