Question

An isosceles triangle has base angles that each measure 52º. Which equation can be used to

find z, the measure of the third angle of the isosceles triangle in degrees?
A. 104 + 2z = 180
B. 104 + z = 180
C. 52 + 2z = 180
D. 52 + z = 180

Answer 1

Answer: I'm not the best at this but the answer that makes the most sense is B. 104+z=180

Step-by-step explanation: A triangle has 2 sides which are both 52 degrees. Add those to get 104 degrees. Now since a triangle has 3 sides we need to find the one other side so no answers with 2z match meaning the answer should be B.
