Line segments xy and zy are tangent to circle o.

which kind of triangle must triangle xyz be?

a) an equilateral triangle
b) an isosceles triangle
c) a scalene triangle
d) a right triangle

Combine points X and O to get segment XO and combine points Z and O to get segment ZO. Segments XO and ZO are radii of the given circle, then they are congruent. Thus, the triangle XOZ is isosceles, that gives you .

Since segments XY and YZ are tangent to the circle, then .

Consider angles ∠ZXY and ∠XZY:

.

Taking into account that

,

you have

.

If twoo angles adjacent to the side are congruent, then this side is a base of isosceles triangle.

correct choice is B.

answer: no idea

step-by-step explanation: i just want points
