Answer:
what are the things at the end.
Step-by-step explanation:
2cos^2 x = 1 + cos 2x
cos^2 x = 1/2(1 + cos 2x)
f(x) = 6cos^2 x - 4 sin 2x = 6(1/2(1 + cos 2x) - 4 sin 2x = 3 + 3cos 2x - 4sin 2x
Answer:
15 CM
Step-by-step explanation:
Both sides are same length proven by the same angles making botrh sides 15 cm
The correct answer is 63 minutes, what you do is divide 36/20 to get 1.8 then multiply 35*1.8 to get 63.
