1. Find the value of x. in the below given diagram

To find the hypotenuse, we use pythagorean theorem, a^2 + b^2 = c^2

3 squared + 5 squared = x squared

x squared = 34

to get x on its own, we need to square root 34, therefore your answer is the square root of 34 inches or 5.83 inches (2dp)

Hope this helps!!
