Question

in the given figure pq || st. then find the value of x + y is.

a) 125°
b) 135°
c) 145°
d) 120°​

Answer 1

Answer:

c

Step-by-step explanation:

x=85°

y=50°

therefore x+y=145°

hence option c

Answer 2

Since PQ ll ST

So PQO is also parallel to ST.

=> Angle x=85°

Now, By Linear Pair Angles,

Angle PQR+ Angle y=180°

=>Angle y=50°

Threfore, x+y=85+50=135°

Therefore the required value is 135°.
