Question

What is the measure of angle c?

A. 30°
B. 70°
C. 110°
D. 40°​

Answer 1

70 degrees

Explanation:

• All triangles have 3 angles that add up to 180 degrees
• How to solve:
• 40 + 70 + a = 180 // make equation
• 110 + a = 180 // add like terms
• - 110 - 110 // subtract 110 on both sides
• a = 70
• 70 degrees

Hope this helps :)

Answer 2

B - 70

Explanation:

The angles in a triangle always add up to 180.

70+40=110

180-110=70
