Answer:
x = 35 degrees.
Step-by-step explanation:
cos x = sin(20 + x)
Using the identity cos x = sin(90 - x):
20 + x = 90 - x
2x = 70
x = 35 degrees (answer).
Answer:
Value of x is 35°.
Step-by-step explanation:
Given:
cos x = sin ( 20 + x )
To find: Value of the x.
We know that [tex]sin\,(90-\theta)=cos\,\theta[/tex]
Consider,
cos x = sin ( 20 + x )
sin ( 90 - x ) = sin ( 20 + x )
Comparing both sides,
90 - x = 20 + x
-x - x = 20 - 90
-2x = -70
x = 35°
Therefore, Value of x is 35°.
