Question

If angle 2 is 97 what is the measurement of angle 1

Answer 1

∠ 1 = 83°

Explanation:

These angles share the same line and ray, so we know that

∠ 1 + ∠ 2 = 180°

Since ∠ 2 = 97°, we can substitute the value for angle 2 and solve for angle 1.

∠ 1 + ∠ 2 = 180°

∠ 1 + 97° = 180°

∠ 1 = 180° - 97°

∠ 1 = 83°

Answer 2

83

Explanation:

The total angle of a flat line is 180. If you subtract the angle of 2 from 180 you get 83 which is the angle of 1.
