Find the missing angle measure in each triangle. Then classify

the triangle as acute, right, or obtuse. Download pdf

6.) right triangle, 53°

7.) obtuse triangle, 120°

Step-by-step explanation:

6.) Add the given angle measures: 90 + 37 = 127

Subtract the sum from 180 degrees: 180 - 127 = 53

The missing angle is 53 degrees and since there was a 90 degree angle, the triangle is right.

7.) Add the given angle measures: 23 + 37 = 60

Subtract the sum from 180 degrees: 180 - 60 = 120

The missing angle is 120 degrees which is greater than 90, so the triangle is obtuse.
