Question

Maria looked at the sketch of a section of roof shown below.

A. A triangle has two congruent angles

B. An obtuse triangle has one obtuse angle and two acute angles.

C. The sum of the measures of the Angles of a triangle is 180.

D. the measure of an exterior angle equals the sum of the measures of its two remote interior angles​

Answer 1

So every triangle has to have an equal of 180 because if you spread it out and take a triangle apart then you can make a straight line, basically you need to have two same angles and one different, like you have in the model. The X is 40 like the other one. Hope this helps you answer the question. (I can’t completely answer but I hope this helps you understand better!)

Answer 2

Answer:

The sum of the measures of the angles of a triangle is 180º.

Which would be 40.
