Question

cos2 30+ sin2 (2x-4)=1
Find x​

Answer 1

Answer:

(Sin Inverse1/2 +4)/2 = x

Step-by-step explanation:

Cos30 = √3/2 and Cos^2 30 = 3/4

So, 3/4 + sin2 (2x-4)=1

=> Sin^2( 2x-4) = 1-3/4 = 1/4

=>Sin^2( 2x-4) = (1/2)^2

=> Sin(2x-4) = 1/2

=> Sin Inverse1/2 = 2x-4

=>(Sin Inverse1/2 +4)/2 = x
