Answer 1

Answer:

The sum of angles is 180.

y=30 ; x = 150

Answer 2

Step-by-step explanation:

First of all we have to focus on the diagram , where you can easily see a property

the exterior angle of a triangle is equal to the sum of opposite interior angles.

so x = 70 + 80

x = 150 degrees

now we have the value of x

x and y are angles on a straight line so their sum must be equal to 180 degrees

Hence , x+y=180

150 +y =180

y= (180-150) degrees

y= 30degree
