Answer :
Answer:
17.5 degrees.
Step-by-step explanation:
sin theta = cos (3theta + 20)
Since sin theta = cos (90 - theta):
90 - theta = 3 theta + 20
-4 theta = -70
theta = 17.5 degrees.
Answer:
17.5 degrees.
Step-by-step explanation:
sin theta = cos (3theta + 20)
Since sin theta = cos (90 - theta):
