Question

If the 3 angles of triangle are 5x -60, 2x +40, 3x-80 then find x

Answer 1

Answer:

x = 28

Step-by-step explanation:

sum of all angles of a triangle is 180

so,

(5x - 60) + (2x + 40) + (3x - 80) = 180

5x - 60 + 2x + 40 + 3x - 80 = 180

5x + 2x + 3x - 60 + 40 - 80 = 180

10x - 100 = 180

10x = 180 + 100

10x = 280

x = 280/10

x= 28
