Question

I need some help ! The options are 25,50,65,130​

Answer 1

25

Explanation:

diameter YZ = 50

OZ = OX = 25

thus, mXZ= 25

Answer 2

XZ=65

Explanation:

so half of the circle would be 180

we need XZ and we know that YW+WX+XZ= 180

we also know that WX and YZ are parallel

WX=50

YW=XZ

YW+XZ=2XZ

WX+2XZ=180

50+2XZ=180

2XZ=130

XZ=65
