I'll draw it now

I need to find the value of Z

Answer 3

What kind of triangle is this?

Answer 4

It has a name when two angles are congruent the triangle is called a(n) ___________ triangle.

Answer 5

Equilateral, right? I'm not sure it didn't say what triangle it is

Close. It is not equilateral. If two angles are congruent then the sides opposite those angles are congruent and if two sides of a triangle are congruent we call this an i__________ triangle.

Answer 7

isosceles

Answer 8

So, what do I do now to find the value of Z?

Answer 9

since you now know this is an isosceles triangle, the sides opposite those congruent angles are the same length.... ie, 2z-15 = 9

just solve for z in the above equaton.

Answer 10

I got z=12,
