Two angles are complementary. One angle is six less than twice the other angle. Find both angles.

• 30 and 60 degrees

• 36 and 54 degrees

• 24 and 66 degrees

• 34 and 56 degrees

If m∠1 = x² - 4x and m∠2 = x + 36, find m∠3.

• m∠3 = 180° - (x² - 4x + x + 36)

• m∠3 = 180° - (x² - 4x - x - 36)

• m∠3 = 180° + (x² - 4x + x + 36)

• m∠3 = 180° + (x² - 4x - x - 36)
