Question

A triangle has congruent angles. Two of the angles measure 68° and 56°. How many degrees are in the third angle?

A. 68
B. 18
C. 56
D. not enough information

Answer 1

C. 56

Explanation:

So if the total amount of degrees in a triangle is 180

(degrees = 180(n-2), d = 180(3-2), d = 180), then 180 = 68 + 56 + x

solve the equation for x

180 = 68 + 56 + x

180 - 68 - 56 = x

x = 56
