Question

3.) Find the supplement of 80.5°
(A) 100.5° (B) 99.5° (C) 89.5° (D) 79.5​

Answer 1

`Angle_2 = 99.5\°`

Step-by-step explanation:

Given

`Angle_1 = 80.5°`

Required

Determine the supplement of the angle

Two angles are said to be supplementary if:

`Angle_1 + Angle_2 = 180\°`

Substitute 80.5° for Angle1

`80.5\° + Angle_2 = 180\°`

Solve for Angle2

`Angle_2 = 180\° - 80.5\°`

`Angle_2 = 99.5\°`

Hence, option B answers the question
