Joe is 72 inches tall and has a 108 inch shadow at the same time martha has a 96 inch shadow how tall is martha

64 inches

Step-by-step explanation:

Given :

(Joe's height / Joe's shadow) = (Martha's height / Martha's shadow)

Let Martha's height = h

72 in / 108 in = h / 96 in

Cross multiply :

108 * h = 72 * 96

h = (72 * 96) / 108

h = 6912 / 108

h = 64 inches

Martha is 64 inches tall.

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
