Answer 1

Hey there!

Answer:

x = 80° and y = 65°

Step-by-step explanation:

Given,

x - y = 15 ..........(i)

2x + y = 225 ...........(ii)

On adding both the equations,

2x + y = 225

x  - y = 15

===========

3x = 240

x = 240 / 3

x = 80°

Putting value of x in eq. (i):

x - y = 15

80 - y = 15

-y = 15 - 80

- y =  - 65

y = 65°

Hope It Helps You!

Answer 2

Answer:

x=80° y=65°

Step-by-step explanation:

x-y= 15°

y=x-15 ..........(1)

2x+y=225°

by equation (1) we get

2x +x-15° = 225°

3x =240°

x=80° y=65°
