Question

Find the missing dimension of the figure below:

18"
18"
9"

Answer 1

√(243)

Explanation:

a2+b2=c2

c2 = Hypotenuse

a2 = Leg

b2 = Second Leg

givens

18 = c2 = Hypotenuse

9 = a2 = One Leg

9 sqaured + b squared = 18 squared

81 + b squared = 324

-81 -81

---------------------------------

b squared = 243

b = square root 243

b = √(243)
