Answer:
Q4: First, third, fifth
Step-by-step explanation:
I'm pretty sure question 5 is the first, and fourth one.
The answer is D. All you have to do is add all of the angles for each choice you're given. It has to add up to exactly 180, because every triangle is 180 degrees.
I believe the answer would be 36.
