Question

If √2 sin (5x -5)° =tan 45°, then the value of (in degrees) is:

A.

14

B.

16

C.

10

D.

12

Correct option is C

Given:

√2 sin (5x -5)° =tan 45°

Formula Used:

tan45=1sin45=12\tan 45^\circ = 1\\\sin 45^\circ = \frac{1}{\sqrt{2}} 

Solution:

√2 sin (5x -5)° =tan 45°

​√2 sin (5x -5)° =1

sin (5x -5)° =1/​√2

​sin (5x -5)° = sin⁡45

5x =50°\degree​​

So, value of x=10°\degree​​
