Question

The last 3

Answer 1

the interior angles of a triangle must add up to 180

Answer 2

Okay, I see now thanks.

Answer 3

For the first and second one, remember that the sum of all angles in a triangle is 180 degrees.
For the third one, apply the concept you use on the first two questions. then, remember that the sum of adjacent angles is 180, so after finding the value of angle 1, you gotta find its supplementary angle to know the answer. ;)
