These angles are supplementary.

Question

1. X and 2. 140°
What is the measure of /_x?
x = [?]°

Answer 1

Supplementary angles are two angles whose measures add up to 180°.

Given that one angle is 140°, to find the measure of angle X, we can use the following equation:

\[ X + 140° = 180° \]

Now, to solve for X, subtract 140° from both sides:

\[ X = 180° - 140° \] \[ X = 40° \]

Therefore, the measure of angle X is 40°.

So, \( x = 40° \).
