Question

Two angles of a triangle measure 27 and 17. What is the measure of the third angle?

Answer 1

The third angle is 136

Explanation:

The three angles of a triangle add to 180

27+17+x = 170

Combine like terms

44+x = 180

Subtract 44 from each side

44+x-44 =180-44

x =136

Answer 2

136⁰

Explanation:

Three angles of a Triangle always addvup to 180⁰

27⁰ + 17⁰ + ×⁰= 180⁰

44⁰ + x⁰ = 180⁰

× = 180 - 44

= 136⁰

Therefore Angle 3 = 136⁰
