Question

Cos x°=sin (3x+10) °

Answer 1

HEY MATE.....!!!
HERE IS YOUR ANSWER..
Simplifying
cos(x) = sin(3x + 10)

Multiply cos * x
cosx = sin(3x + 10)

Reorder the terms:
cosx = ins(10 + 3x)
cosx = (10 * ins + 3x * ins)
cosx = (10ins + 3insx)

Solving
cosx = 10ins + 3insx

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Divide each side by 'osx'.
c = 10ino-1x-1 + 3ino-1

Simplifying
c = 10ino-1x-1 + 3ino-1

Reorder the terms:
c = 3ino-1 + 10ino-1x-1

Answer 2

cos x = sin(3x+10)
sin(90-x) = sin (3x+10)
90-x= 3x + 10
80= 4 x
x = 80/4
=20
