Question

8. The figure-3 given below is a parallelogram CNPS. Find the measure of angles a, b and c. Also, represent them on the diagram. N C a 60° 5cm 110° S 6cm Figure-3​

Answer 1

Answer:

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  

∘
