GX is the angle bisector. Answer is C
Answer:
Vertical
Step-by-step explanation:
Intersecting lines form Vertical angles.
Answer:
The answer is (π/4)*r
Step-by-step explanation:
Formula length of arc when the angle given is in radian as the case given
s = r*θ
s = arc length (in radians)
r = radius
θ = central angle in radians
But when the angle given is in degrees the length is expressed as
s= 2πr*(θ/360)
I think the answer would be c
