Abcd is a triangle , what is the value of x?

You’re going to want to use the pythagorean theorem (a^2+b^2=c^2). Start with what you know your hypotenuse is 53 ft (c) and one of your sides is 45 ft (a). Plug in the equation: (45^2+b^2=53^2). Next square each side: (2025+b^2=2809). Then: (b^2=784). Finally square root: (b=28) So your answer is x=28 ft.

53^2 = 45^2 + x^2
x^2 = 784
x = 28 ft
