Solve the equation sin (x° - 20°) = cos 42° for x, where 0 < x < 90. a. 62 b. 22 c. 68 d. 28

Answer

Find out the value of x.

To prove

As given

sin (x - 20°) = cos 42°

Now using the property .

cos y =  sin (90 - y )

Thus

sin (x - 20°) = sin (90° - 42°)

x - 20° = 48°

x = 48° + 20°

x = 68°

Therefore the value of x is 68° .
