Two angles in a triangle measure 33° and 112° What is the measure of the third angle?

35°

55°

145°

215°

Step-by-step explanatiaon:

angles in a triangle have a total of 180 degree.

33+112=145

180-145=35

answer：35°

35°

Step-by-step explanation:

Let's call the third angle x

The sum of interior angles in a triangle is equal to 180°

So the sum of 33° + 112° + x = 180°

145° + x = 180°

x = 180 - 145

x = 35°
