Question

Your uncle is making you a desk for you to take to college. one side of the desk is 48 inches and the diagonal length is 53.7 inches. what is the length of the other side of the desk? 12 inches 23.8 inches 17.4 inches 24 inches

Answer 1

let
a------> length of the desk
b-------> wide of the desk
D------> diagonal of the desk

we know that
D=53.7 in
a=48 in
b=?
applying the Pythagoras Theorem
D²=a²+b²
b²=D²-a²----> b²=53.7²-48²----> b²=579.69-----> b=√579.69
b=24.08 in------> 24 in

the answer is
24 in
