Determine the value of x.​

Mathematics
1 answer:
telo118 [61]3 years ago
5 0

Answer:

10

Step-by-step explanation:

This triangle is isosceles, same as the little triangle.

If one side of the little triangle is 3x, then the little side with the tick (let's name it a) is also 3x.

That means the longer side, 2a, is 6x

This triangle is isosceles, so 6x = 4x + 20

Now, if we solve that, x = 10

The answer is 10

Hope this helps :)

Have a good day!

The height of a pyramid-shaped sculpture with a square base is one half the length of each side. The volume of the sculpture is
Nimfa-mama [501]

The volume of a pyramid is V = 1/3 x base length^2 x height

Let X = base length.

We are told the height is 1/2 the length, so height would be 1/2x

Now we have:

972 = 1/3 * x^2 * 1/2x

Simplifying we get:

972 = 1/6x^3

Multiply both sides by 6:

5832 = x^3

Take the cube root of both sides:

x = 18

The length of the base is 18 inches.

The height is 1/2 that, so the height would be 18/2 = 9 inches.
