Answer:
WV = 5
Explanation:
The pythagorean theorem formula is a^2+b^2=c^2.
a and b being the two legs and c being the hypotenuse (the longest side of the right triangle.)
We can count the boxes for each of the legs. 3 and 4
Using this, we can plug this in and get 3^2+4^2=c^2
9+16=25
sqrt(9+16)=sqrt(25)
WV = 5
Hope that Helps!!!
