Question

if the angles in degrees of a traingle are x,3x+20 and 6x, the traingle must be​

Answer 1

Answer:

x + 3x + 20 + 6x = 180

= 10x + 20 = 180

= 10x = 180 - 20

= 10x = 160

x = 160/10

x = 16

Answer 2

Answer:

according to angle sum property of a triangle

x+3x+20+6x=180

10x+20=180

10x=160

x=160/10

x=16
