Question

Let Triangle XYZ be circumscribed on Circle R, and let XS = 7, SY = 23, and YZ = 79. Select the best answer for each calculation. Calculate XZ.

Answer 1

use geometric properties:
If two lines from a common vertex are both tangent to a circle then the lines are equal distances from the points tangent to the vertex.
In other words
ZU = ZT
YU = YS
XT = XS
that will help you solve for XZ
