(9 x² + 8 x + 2) - ( 4 x² + 2 x -5 )
= 9 x² + 8 x + 2 - 4 x² - 2 x + 5
= 5 x² + 6 x + 7
Answer:
angle 1 = 51 degrees
angle 2 = 18 degrees
angle 3 = 123 degrees
angle 4 = 39 degrees
Step-by-step explanation:
angle 2 = 90-72 = 18
angle 3 = 180 - 57 = 123
angle 4 = 180 - 123 - 18 = 39
angle 1 = 90 - 39 = 51
