Question

Find the missing angle measurement the complementary angles add up to 90 degrees (right angle) supplementary angles add up to 180 degrees ( straight angle)

Answer 1

Let x be the missing angle measurement.

If the two angles are complementary, then x + 30 = 90

x = 90 - 30 = 60 degrees

If the two angles are supplementary, then x + 60 = 180

x = 180 - 60 = 120 degrees

Therefore, the missing angle measurement can be 60 degrees or 120 degrees.
