True. Both methods correctly verify the trig identity
Answer:
36.45 cm
Step-by-step explanation:
You can automatically assume that if it was 20% cut off, Wendy's hair would've been 36 cm. Multiply 45 by 0.19 to get 8.55 since that is how much Wendy's hair is being cut off. Subtract that number from 45 to get your final answer which is 36.45 cm.

Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
