Step-by-step explanation:
2x +2° = 3x - 52° { being vertically opposite angles }
3x - 2x = 52° + 2°
x = 54°
Hope it will help :)
Answer: -1/2
Step-by-step explanation:
Use double-angle identities:
cos(2θ)=cos^2θ−sin2^θ
cos(2θ)=1−2sin^2θ
cos(2θ)=2cos^2θ−1
sin(x)=1/2
cos(2x)=1−2sin^2x=1−2(1/4)=1/2
cos(4x)=2cos2^(2x)−1=2(1/4)−1=-1/2
