Q  10) If the sum of an angle and 11 times its complement is 510, then the angle is °
ANS 10) If the sum of an angle and 11 times its complement is 510, then the angle is °

Hi Sanjay,

 

Lets assume that angle is x. Its complement angle = 90 - x.

Since sum of the angle and its complement is 510,

x + 11 (90-x) = 510

x + 990 - 11x = 510

10 x = 990 - 510

10 x = 480

Hence x = 48.
