Two supplementary angles add up to 180°. So the measure of the angle supplementary to 38° is 142°.

Answer:

The larger angle is \(142\) degree

Explanation:

The sum of supplementary angle is \(180\) degree.

Given

Angle \(A = 38\) degree

Let the other angle be "B"

Angle \(A +\)Angle \(B\)\(= 180\)degree

\(38 + B = 180\\B = 180 - 38\\B = 142\) degree

The larger angle is \(142\) degree.
