Question

Can you please help me with 20th one

Answer 1

Answer:

We know that parallelogram's diagnols bisect each other

therefore

20 = y + 7

y = 13

and

16 = 13 + x

x = 3

x = 3 & y = 13

hope it helps :-)

Answer 2

With Pythagoras theorem, find all the sides and u will get few equations. Now from that equations, put the value as required.
