These angles are supplementary.

Question

1. X and 2. 86°
What is the measure of /_x?
x = [?]°

Answer 1

Supplementary angles are angles that add up to 180 degrees. Given that one angle is 86°, we can find the measure of angle X by subtracting 86° from 180°.

So we can calculate:

\[ x + 86° = 180° \]

Subtracting 86° from both sides gives:

\[ x = 180° - 86° \] \[ x = 94° \]

Thus, the measure of angle X is:

\[ x = 94° \]
