These angles are supplementary.

Question

100 degress and an X
What is the measure of the X?
X = [?]

Answer 1

Two angles are supplementary if the sum of their measures equals 180 degrees.

Given that one angle is 100 degrees, we can find the measure of angle X by using the following equation:

100 degrees + X = 180 degrees.

To solve for X, subtract 100 degrees from both sides:

X = 180 degrees - 100 degrees, X = 80 degrees.

Therefore, the measure of X is 80 degrees.
