Question

Which equation is true about the measure of the angles of the triangle?the measure of angle prq is equal to 100 degreesthe measure of angle prq is equal to 90 degreesthe measure of angle pqr plus the measure of angle qpr is equal to 80 degreesthe measure of angle pqr plus the measure of angle qpr is equal to 70 degrees?

Answer 1

I believe this question is missing an image. However, I will just tell how how to solve such question and you can apply this solution to the triangle you have.

In any given triangle, the sum of the measure of the three angles must be equal to 180 degrees.
Therefore, for a triangle pqr:
measure angle pqr + measure angle prq + measure angle rqp = 180 degrees

If you have one angle given, then the sum of the other two angles will be equal to 180 - measure of the given angle.

If you have two angles given, then the measure of the third angle will be equal to 180 - the sum of the other two angles.
