Question

If sin 3 theta = cos ( theta - 6 ) and 3 theta and theta - 6 are acute angles, find the value of theta

​

Answer 1

Answer:

Step-by-step explanation:

sin 3Ф = cos ( Ф - 6)

sin 3Ф = sin ( 90 - Ф + 6) [we know, sin(90 - Ф) = cos Ф

3Ф = 90 + 6 - Ф

3Ф + Ф = 96

4Ф = 96

Ф = 96/4

Ф = 24
