Question

Help me in geometry

Answer 1

A triangle's angles should equal 180°. We are given two of them that together equal 145°. 180-145=35. Since we are trying to find the other side of a straight line which should equal to 180° also, 180-35=145. So, it would be D. 145

Answer 2

C because it is an obtuse angle and u can subtract the mass amount
