Answer:
A. supplementary
Step-by-step explanation:
Note the angle measurements of BOC. m∠BOC = 90°
Now note that line FC is a straight line, which makes it's measurement = 180°
Subtract 90 from 180: 180 - 90 = 90°
Both are 90°, which, when combined makes a supplementary angle.
Answer:
there that should help
Step-by-step explanation:
C(1;2)
a = 1
b = 2
r = 4
(x-a)² + (y-b)² = r²
(x-1)² + (y-2)² = 4²
(x-1)² + (y-2)² = 16
Answer:
right
Step-by-step explanation:
The box in the lower corner means that the angle is equal to 90 degrees, which means the angle is a right angle
