Answer 2

Complementary Angles:

The sum of two complementary Angles is 90°.

Given:

If two complementary Angles differ by 18°.

To Find:

The angles.

Assumption:

Let the angles be x and x + 18.

Solution:

x + x + 18° = 90°

or, 2x = 90° - 18°

or, x = 72/2

or, x = 36°

Answer:

x = 36°

x + 18° = 36° + 18° = 54°

Option A. 36°, 54° is the correct answer.
