Question

10. Find x and y, if / || m || n.
85°
(6x + 5y)
90°
(6x + 6y)
m
n​

Answer 1

Answer:

x =10⁰ and y=5⁰

Step-by-step explanation:

6x+5y=85⁰(alternate interior angles)

6x+6y=90⁰(corresponding angles)

let's solve above equations by elimination method

from equation 2 we have

x=15-y

on putting this value in equation 1 we get

6(15-y)+5y =85⁰

on solving above equation we get y as 5⁰ and x as10⁰
