Question

Two interior angles of a triangle each measure 34 what is the measure of the third interior angel?

Answer 1

112°

Explanation:

I have made the angles into these:

m<A=34°

m<B=34°

m<C=x°

All interior angles in a triangle add up to 180°. To find the answer, add the angle measure for the given angles, then subtract that from 180. I will use "x" to substitute for the value of the third angle.

(34+34)+x=180

68+x=180

180-68=112

So, m<C (or "x") should equal 112°.
