Question

If sin(9x-8) = cos(4x+7) what is the X value

Answer 1

Step-by-step explanation:

QUESTION :-

If sin(9x-8) = cos(4x+7) what is the X value.

SOLUTION :-

FIND IT :-

what is the X value?

solve :-

sin(9x-8) = cos(4x+7)

solve the Equation :-

sin(9x-8) = cos(4x+7)

sin(9x-8) = sin(90-(4x+7))

sin(9x-8) = sin(83-4x)

9x-8 = 83 - 4x

13x= 91

x=7°
