Question

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

Answer 1

Answer:

$Angle_2 = 99.5\°$

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
