Sin(60) = ¹/₂√3
cos(60) = ¹/₂
tan(60) = √3
The answer is D.
Answer:
(1,3)
Step-by-step explanation:
Rotating clockwise means that you're rotating by a negative angle measure. The rule for rotating -90 degrees is (x,y)->(y,-x). X is (-3,1) so X' should be (1,3) since you negate -3 to get 3 and switch the x and y coordinates.
We convert degrees to radian by multiplying by (
)
= (345) × (
)
= (
) × (π)
= 1.9166π
= 1.9166 × 3.14
= 6.018 rad
≈ 6.02 rad
