Solve for x. Then find the side lengths of the triangle. If needed, round to the nearest tenth of a foot. 40 ft
Bx ft
6x ft
side lengths =
ft and

The side lengths are 17.9 feet and 35.8 feet

Step-by-step explanation:

Given lengths are;

40 feet, 3x feet and 6x feet

As the given triangle is right angled,

a = 3x, b = 6x and c = 40

Using Pythagorean theorem;

Dividing both sides by 45

Taking square root on both sides

Side lengths = 3x = 3(5.96) = 17.9 feet

and

6x = 6(5.96) = 35.8 feet

Hence,

The side lengths are 17.9 feet and 35.8 feet
