Question

find out the value of m and the three angles,if the angle in the triangle are m-40, m-20, m+60???​

Answer 1

Step-by-step explanation:

m - 40 + m - 20 + m + 60 = 180

(Measures of angles of a triangle)

3m = 180

m = 180

3

m = 60

Measures of angles,

m - 40 = 60 - 40 = 20

m - 20 = 60 - 20 = 40

m + 60 = 60 + 60 = 120
