Answer 1

Answer:

Let the angle be x then the other angle which is supplement of angle x will be 2x.

Now Two Angles are Supplementary when they add up to 180 degrees.

Therefore

x + 2x = 180°

3x = 180°

x= 60°

Therefore the desired angle is 60°

Answer 2

4. From the figure

We know that the straight line makes the angle is 180°

So that,

50+35+b-20+10=180°

75+b=180

b = 180-75

b = 105° Answer.

I hope that helps you
