In this figure, POR and QOR from a linear pair. if x:y =2:3 ,find the value of x and y. |
|
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 |
