mXSZ=220∘



What is the measure of ∠XYZ ?

Respuesta :

The measure of an angle formed by two tangents intercepting at a point outside a circle is equal to half the difference of their intercepted arcs.
XYZ = 1/2(XSZ - XZ)
XYZ = 1/2 (220 - 140)
XYZ = 1/2 (80)
XYZ = 40

The measure of angle XYZ is 40 degrees.

Hope this helps =)
