Question

can any one give me the answer fast​

Answer 1

The sum of measure of all angles of a triangle is equal to 180°.

(x+20)+(2x-30)+(3x-50) = 180

6x-60 = 180

6x = 180+60 = 240

x = 40

Thus, the angles are;

x+20 = 40+20 = 60°

2x-30 = 2(40)-30 = 80-30 = 50°

3x-50 = 3(40)-50 = 120-50 = 70°

Answer 2

= x+20+2x-30+3x-50

= 6x-80+20

= 6x-60 = 0

= x = 60/6

= x = 6
