Question

If x and y be the angles forming a linear pair such that x − y = 800 , then y is equal to

Answer 1

Answer:

Since ∠POR and ∠QOR form a ;inear pair.

∴∠QOR+∠POR=180°

⇒x+y=180°.....(1)

Also,

x−y=80°.....(2)(Given)

Adding equation (1)&(2), we have

2x=260°

⇒x=  

2

260°

​  

=130°

Substituting the value of x in equation (1), we have

130°+y=180°

⇒y=180°−130°=50°

Answer 2

y = 450 as x and y form alinearpair to create 450 and 350 is 800
