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

answer is

c) 4

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
