Question

if the supplement of an angle is 20 more than the angle find them​

Answer 1

Answer:

According to the question, 3 times the complement of the angle = 20° more than it's supplement.

Answer 2

Step-by-step explanation:

Here,

let the angle be x and ( x + 20 )

than,

x + x + 20 = 180 °

2x = 180 - 20

2x = 160

x = 160 / 2

x = 80 °

and ,

other angle is x + 20

= 80 + 20

= 100°
