Answer 2

Answer:

here is your answer.

Step-by-step explanation:

4) As you can see in figure the three angles are on a straight line and make linear pair.

So, 2y+10⁰+3y-10⁰+40⁰ = 180⁰

5y+40⁰ = 180⁰

5y = 180⁰-40⁰

5y = 140⁰

y = 28⁰

2) here, CP = 150-25 = 125

profit % = profit / CP × 100

= 25/125×100

= 20%
