Question

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

Answer 1

Answer:

83

Step-by-step 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.

Answer 2

Answer:

∠ 1 = 83°

Step-by-step 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°
