Jacks tent is shaped like an isosceles triangle. The height of the measures 7 feet in the diagonal side measures 9 feet. Find the length of the tent's base.

The length of the tent's base is

Explanation:

The tent is shaped like an isosceles triangle and measures 7 feet.

Since, isosceles triangle has two equal sides, the two sides of a triangle are 7 feet.

It is also given that the diagonal measures 9 ft.

Now, we shall determine the length of the tent's base.

Let x denote the length of the tent's base.

The image of the isosceles triangle having these measurements is attached below:

Using Pythagorean Theorem, we have,

Taking square root on both sides,

Thus, the length of the tent's base is
