Pythagorean Theorem: Finding the Missing Leg
2
Open Ended
3
Find the measure of the hypotenuse: (round to the nearest tenth)
a2 + b2 = c2
52 + 102 = x2
25 + 100 = x2
125 = x2
√125 = √x2
11.2 = x
4
Find the measure of the leg:
(round to the nearest tenth)
a2 + b2 = c2
82 + x2 = 202
64 + x2 = 400
x2 = 336
√x2 = √336
x = 18.3

If you got this problem wrong:
Chances are you didn't divide the base by 2 to get the leg of one of the triangles to be 6!
