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.

x+ 90 + 5x = 180
6x= 90
x= 15 (A)
