Step-by-step explanation:
Answer:
Step-by-step explanation:
g(-2) = 5 - 3(-2)^2 = 5 - 3(4) = 5 - 12 = -7
The sine of 1/2 the angle = 13 / 32
so this angle = 23.9695 degrees
Therefore the required angle = 2 * 23.9695 = 47.939 to 3 DP's.
Answer:
the answer is

cause sin²x= 2/25
so cos²x would be 1-2/25= 23/25
then cos x is what I wrote as the answer
