Step-by-step explanation:
x = 1/2 Arc AB ( Relation between inscribed angle and corresponding arc)
x = 1/ 2 * 124
x = 62°
y = x ( Inscribed angles on standing on same arc are equal)
y = 62°
Hope it will help :)
Answer:
XY=8
Step-by-step explanation:
In △XYZ, XY=XZ
It is isosceles triangle whose equal sides are XY=XZ
We are given,
XY=2a
YZ=3a+1
XZ=5a-12
XY=XZ
So, 2a=5a-12
Solve for a,
2a-5a=-12
-3a=-12
a=4
Now we put a=4 into XY=2a
So, XY=2(4)=8
