These two angles are complementary.

Question

1. 19° and 2. X
What is the measure of /_x?
/_x = [?]°

Answer 1

Two angles are complementary if the sum of their measures is 90 degrees. Given that one angle is 19° and the other angle is X, you can find the measure of X by using the equation:

\[ 19° + X = 90° \]

To find X, subtract 19° from both sides:

\[ X = 90° - 19° \]

Calculating this gives:

\[ X = 71° \]

So, the measure of angle X (/_x) is:

\[ /_x = 71° \]
