Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
Answer:
circle S radii SU, ST, SR
Circle U radii UT, US, UR
Step-by-step explanation:
Radii start in the middle of the circle to the end of the circle.
Answer: The perimeter of the rectangle is 28 centimeters.
Step-by-step explanation: I hope this helps-
It is the same as multiplying by 2/3, the equation being 2/3n n being the number
solve for y by subtracting 3x from each side
-4y = -3x+8
divide by -4
y = 3/4 x -2
