Question

Two angles of a triangle measure 75° and 40°. What is the degree measure of the third angle?

Answer 1

the angles of a triangle always equal 180 so

75+40+x=180

115+x=180

-115

x=65

the other angle is 65

Hope This Helps!!!

Answer 2

65°

Explanation:

let the third angle be x

so, sum of all angles of a triangle = 180°

x° + 75° + 40° = 180°

x + 115° = 180°

x = 180° - 115°

x = 65°
