When sum of two angles is 90°, then each of those two angles will be considered to be the complementary angle of each other.<u>Example</u> : 60° and 30° are two angles, and their sum is 90°. So, 60° and 30° are complementary angles.
____________________
<h3><u>Explanation</u> :-</h3>
Measure of an angle is 13.8° more than the measure of it's complementary angle. We are asked to find measure of each angle!
<h3><u>Solution</u> :-</h3>
One of the complementary angles be "x" . Then the other angle becomes " (x + 13.8)° "
Sum of these two angles is equal to 90° . Since they are complementary angles.
<u>Then</u> –
The measures of the two given angles is 38.1° and 51.9°.
