Question

5 mi
a
3 mi
What is the length of the missing leg ?

Answer 1

A=4

Explanation:

you use the Pythagorean Theorem,

a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.

Here is how I solved for Leg a using the Pythagorean Theorem.

Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]

Leg a = sqrt[ (5)2 - (3)2 ]

Leg a = sqrt[ 25 - 9 ]

Leg a = sqrt[ 16 ]

Leg a = 4
