Please help me with the middle question

Gwar [14]

The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.

65 + 15 = 80

180 - 80 = 100 = Angle C.

It says to list them from smallest to greatest.

<B = 15, <A = 65, <C = 100
