Question

BRIANILEST!!!Hassan lined up the interior angles of the triangle along the line below.

Answer 1

Your answer would be 30°. This is because angles on a straight line add to 180°, and if you add 112 and 38 you get 150°, which we can then subtract from 180 to get 30°.
Angles in a triangle also add up to 180°, so the same logic applies there except adding 112 and 30.
I hope this helps! Let me know if you have any questions :)

Answer 2

A straight line = 180 degrees.

Subtract the 2 known angles from 180:

180 - 112 - 38 = 30 degrees
