These angles are supplementary.

Question

1. X and 2. 20°
What is the measure of /_x?
x = [?]°

Answer 1

Two angles are supplementary if the sum of their measures is equal to 180°. Given that one angle is 20°, we can find the measure of angle X using the following equation:

\[ X + 20° = 180° \]

To find X, subtract 20° from both sides:

\[ X = 180° - 20° \] \[ X = 160° \]

Thus, the measure of angle X is:

\[ X = 160° \]

So, the answer is \( x = 160° \).
