Find the value of x.
nekit [7.7K]

Answer:

B

Step-by-step explanation:

Since this right angled triangle has two angles of 45, so according to theorem sides opposite to equal angles are equal

Applying Pythagoras theorem

(4√2)^2=(x)^2+(x)^2

32=x^2+x^2

32=2x^2

x^2=32/2

x^2=16

Taking sq root on both sides we get

x=4
