Answer:
If you reduce this to the lowest terms you get 4/9
Step-by-step explanation:
In order to simplify the fraction 32/72, you can divide each term by 8.
32/8 = 4
72/8 = 9
Therefore, we get 4/9

Applying the trig formula: sin a = cos (90 - a)
cos (2x + 8) = sin (x + 37) = cos (90 - x - 37) = cos (53 - x)

Check by calculator.
x = 15 --> sin (x + 37) = sin 52 = 0.788
cos (2x + 8) = cos (38) = 0.788. Proved
x = - 61 --> sin (x + 37) = sin (- 24) = - sin 24 = - 0.407
cos (2x + 8) = cos (-122 + 8) = cos (- 114) = - 0.407. Proved
