Question

if cos2theta = sin(theta-12), where 2theta and (theta-12) are both acute angles, then the value of theta?
PLEASE ANS​

Answer 1

Answer:

34

Step-by-step explanation:

cos2theta = sin ( theta -12)

sin(90-2theta) = sin (theta - 12)

90 -2 theta = theta -12

90 +12 = theta + 2 theta

102 = 3 theta

theta = 34
