Question

RISK is a parallelogram. Find values w, x, y and z.​

Answer 1

Step-by-step explanation:

In parallelogram RISK,

∠RKS+∠ISK=180

∘

120

∘

+∠ISK=180

∘

∠ISK=60

∘

Adjacent angles are supplementary

Also, opposite angles are equal

In parallelogram CLUE, ∠ULC=∠CEU=70

∘

Now,

x+∠ISK+∠CEU=180

o

x+60

∘

+70

∘

=180

∘

x=50
