Answer:
(a) 1/2
Step-by-step explanation:
The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...
(x, y) = (cos(α), sin(α))
When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.
A. 5y = x
b. 5(6.5) = $32.50
c. 47.50/5 = 9 hours and 30 minutes
d. 9y = x
e. 9(8.5) = $76.50
f. 49.50/9 = 5 hours and 30 minutes
the simplest form is n • (3n3 - 8)
Step-by-step explanation:
2x + 1 + x - 13 = 180° because these angles are supplementary
3x - 12 = 180°
3x = 180 + 12
3x = 192 divide both sides by 3
x = 64
2x + 1 ➡ 2 × 64 + 1 = 129°
x - 13 ➡ 64 - 13 = 51°
