Question

please answer urgent question no 10​

Answer 1

Answer:

Let the smaller angle be x

Let the greater angle be x+20

x+x+20=180°

2x+20°=180°

2x=160°

x=80°

Smaller angle =80°

Greater angle=80°+20°=100°

Answer 2

Answer:

So the measures of angles are 80 and 100

Step-by-step explanation:

Let the required angle be x

So other angle will be (x+20)

now the equation, we get is- x+(x+20)= 180

= x+x+20=180

2x=180-20

x=160/2

x=80

and x+20=100
