Question

In the following figure of a ship, ABDH and CEFG are two parallelograms. Find the value of x. H G F A 70 30° 130° to E B D C Fig. 5​

Answer 1

Answer:

.Answer:

Adjacent angles of parallelogram are supplementary and opposite angles are equal.

So, In parallelogram ABDH

∠A+∠B=180

o

∠D=∠A=180−∠B=180−130=50

o

Also, In parallelogram CEFG,

∠C=∠F=30

o

Hence , in ΔCDX

∠C+∠D+∠X=180

o

30+50+x=180

∠x=180−80=100
