Answer:
(x, y) = (1/2, -√3/2)
Step-by-step explanation:
The coordinates on a unit circle of the intersection of the terminal ray of angle α are ...
(x, y) = (cos(α), sin(α))
For α = 5π/3, the point on the unit circle is ...
(x, y) = (cos(5π/3), sin(5π/3)) = (1/2, (-√3)/2)
Answer:
x≤-4 or x≥0.5
Step-by-step explanation:
Right triangle
Use Sohcahtoa
Given hypothenuse = 10
Adjacent = x
And angle degree of 52
You can use Cosine
Cos(52) = x/10
0.6156614753 = x/10
x = 6.156614753
Round to nearest tenth
Solution: 6.2
