Answer 1

Answer:

We will use opposite entirior propertie

As , property says sum of 2 enterior angles is equal to the outer angle

Step-by-step explanation:

First . 120 degree

Second . 120 -60 =60

third. we will use leniar pair (2 angles in one line whos sum are 180 ) for getting b angle which will be 130-180=50 degree

fourth. we will use angle sum property to find x , which says (sum of all enterior angles in a triangle is 180 degree) so , x will be 20+20=40-180=140.

Answer 2

Answer:

1 part ans. x =120⁰

2 part ans. y =60⁰

4 part ans. y = 140⁰
