Question

the measure of two angles of a triangle are 35 and 45 what is the measure of the third angle of the triangle

Answer 1

The answer is 100. 180-35-45=100

Answer 2

 If you pull the edges of the right angle down it makes a straight line. 

Therefore, the angles in a triangle add up to 180° 

So, 35 + 45 = 80 

Then, 180 - 80 = 100 

The third angle = 100°
