Question

You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees

Answer 1

B) 70 degrees

Explanation:

The sum of angles in a triangle = 180 degrees

We are given 2 angles in the triangle = 70° and 40°

The measure of the third angle is

180° = 70° + 40° + 3rd Angle

3rd Angle = 180° - ( 70° + 40°)

= 180° - 110°

= 70°

The measure of the other angle is 70°

Option B is the correct option.
