Question

In triangle QRS, the measure of

angle Q is 70º. Angle R is
congruent to angle S. What is the
measure of angle R in degrees?

Answer 1

62

Explanation:

Answer 2

55 degrees :)

Explanation:

all triangles add up to 180 degrees.

we already have 70 degrees and since <S = <R they are the same # of degrees.

subtract 70 from 180 and we get 110.

divide 110 by 2=55

<S 55

<R 55

<Q 70
