Answer:
10 feet
Step-by-step explanation:
You use the pythagorean theorem to find the missing side of a right triangle.
side^2 + side^2 = hypotenuse ^2
6^2 + 8^2 = X^2
36 + 64 = 100
square root of 100 = 10
Length * Width = Area
Width = Area / Length
W = 42 / 16.8
W = 2.5 inches
Im pretty sure it is length times width :)
X = 4.8 cm
You have to find the height then use the height to find the x value
