Triangle measurement

Question

Solve this exercise using the fact that the sum of the measures of the three angles of a triangle is 180°. In a​ triangle, the measures of the three angles are​ x, x-10​, and x+40. What is the measure of each​ angle?

Answer 1

Answer 2

x + x-10 + x+40 = 3x +30 = 180

3x = 180-30 =150

x =150/3 = 50

the 3 angles are 50, 40 and 90 degrees

x=50

x-10=50-10 =40

x+40 = 50+40 = 90
