Question

Solve 18,19,20.please solve these three sums

Answer 1

18. a) In parallelogram TRUE
TE = RU ( opposite sides are equal in parallelogram)
33=8y +1
33-1= 8y
32 = 8y
y = 4
Also, UE = RT
70= 5x
x= 14

b) In parallelogram WIND
24 = y+4 ( Diagonal s of parallelogram bisect each other )
y = 24-4 = 20
Also,32 = x+y
32 = x+ 20
32-20 = x
x= 12
