Question

(14. In parallelogram PQRS,<P = (3x – 20)°,<Q = (y +15)", <R =
(x +40)", find the value of x and y.​

Answer 1

Answer:

x=15 and y=75

Step-by-step explanation:

<P=<R(opposite angles of parallelogram are equal)

3x-20=x+40

3x-x=40+20

4x=60

x=60/4

x=15

<P=3*15 +20=45+20=65

PS II QR with PQ as transversal

<P+<Q=180(co interior angles)

65+x+40=180

105+y=180

y=180-105

y=75
