Question

If sin (20+x) = cos 60 , find the value of x

Answer 1

Answer:

Step-by-step explanation:

since

sin(20 + x) = cos60

sin(20 + x) = cos(90 - 30

sin(20 + x) = sin 30

so

20 + x = 30

x = 10

Answer 2

hey mate here is your answer

sin(20+X)=cos 60

sin(20+X)=cos(90-30)

sin(20+X)=sin 30

so 20+X=30

X=10
