Answer:
a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2
b) 120°
c) sin = -1/2 = -30° or 330° both are same
Use the trig circle which i have included in the answer to better understand trig angles
hope that answers your question
I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.
good luck!!
All this question is asking you to do is multiply 65 and 7. The 7 comes from the amount of days in a week. The product of these numbers is 455.

Answer:
x = 6
y = 4
Step-by-step explanation:
Apply the angle bisector theorem to solve for x and y respectively.
✔️4/(9 - x) = 8/x
Cross multiply
4*x = 8(9 - x)
4x = 72 - 8x
Add 8x to both sides
4x + 8x = 72
12x = 72
12x/12 = 72/12
x = 6
✔️y/2 = 6/3
Cross multiply
3*y = 6*2
3y = 12
3y/3 = 12/3
y = 4
Yes, that is the correct answer. 27-12=15
