x + 90 + 5x = 180

6x = 90.

x = 15.

A is the best answer.

Solution



Given:
    • In the given figure, y = 5x

To find:
    • The value of angle x

Approach and Working:
We know sum of all the angles on a straight line is 90°
Hence, we can say x + 90 + y = 180
    Or, x + y = 90
    Or, x + 5x = 90
    Or, x = \(\frac{90}{6}\) = 15°

Hence, the correct answer is option A.

Answer: A
