Question

14. Angles x & y forms a linear pair and x - 2y = 30 degrees, the value of y is 1p


a) 50
B) 110

C) 210
D) 60​

Answer 1

a)50 is the correct option

i) x+y=180

x - 2y = 30

ii) x= 30+2y

putting (i) in (ii)

30+ 2y +y = 180

3y= 180-30

3y = 150

y= 50 degrees

pls mark brainliest and i will follow you

Answer 2

Answer:

a) 50 degrees

Step-by-step explanation:

We all know that linear pair = Sum of two angles = 180

=> x + y = 180 __(1)

Given that ..,

  x - 2 y = 30 __(2)

By substracting eq(2) from eq(1), we get..,

3 y = 150

=> y = 50
