Question

The measures of angles of a triangles
are x;(x-20°) and (x-40°). Find the
measure of each angle.​

Answer 1

Answer:

80°, 60°, 40°

Step-by-step explanation:

sum of all angles of triangle= 180°

x + (x - 20) + (x - 40) = 180

x + x - 20 + x - 40 = 180

3x - 60 = 180

3x = 180 + 60

3x = 240

x = 240/3

x = 80°

therefore the angels are

x = 80°

x - 20 = 80 - 20 = 60°

x - 40 = 80 - 40 = 40°

verification

80 + 60 + 40 = 180°

hope you get your answer
