Question

if the measure of two angles of a triangle is 50° and 45° , then find the measure of the third angle of the triangle​

Answer 1

By Angle Sum Property:

In triangle ABC, <A + <B + <C = 180*

Therefore,

50* + 45* + <C = 180*

<C = 180* -(50*+45*)

<C = 180* - 95*

<C = 85*

Thus, the measurement of the third angles is 85*.

Answer 2

Step-by-step explanation:

let the unknown angle to be x

sum of three sides of triangle is 180degree

therefore,

45+50+x = 180

95+x = 180

x = 180-95

x =85
