Answer:
use desmos and type in the equation to get the graph
Step-by-step explanation:
Clearly

corresponds to a point on the fourth "circle" in the plane.

is a rotation of 120 degrees counter-clockwise relative to the positive side of the horizontal axis, which corresponds to a clockwise turn of 360 - 120 = 240 degrees.
This means (C) is the answer.
Answer:
100 square ft.
Step-by-step explanation:
The initial area of the rug is 125 ft (12.5x10)
you take the area (125) and multiply it by 1/5, or 20%. you get 25.
You then subtract 25 from 125 as the question asks to reduce the carpet by one fifth
The new rug is 100 square feet
Complementary angles = two angles that add to 90° complement each other.
So, angle x = 3y+18
y= complementary angle
(3y + 18) + y = 90
4y+18 = 90
4y=72
y=18°
x= 3y+18
x= 3(18) +18
angle x = 72°
7 - 4 = 3 that will be your answer
