Answer:

X=1 m

X= 0.81 m

Step-by-step explanation:

for the first X you must put in a proportion like this

38:8=4:X

X=(4×8)/38= 1 m

for the second one's you could use Pythagorean theorema

finding the diagonal of the biggest rectangle and you must put the diagonals in proportion whit the 2 sides

32:4=Y:32.9

Y=(32×32.9)/4=4.1 m (diagonal of the smallest rectangle)

} \sqrt{ {4.1}^{2}  -   {4}^{2} }  = 0.81m

use an other time the Pythagorean theorema and you find the other option

The area of the given square pyramid is:

total area = 1,100 inches squared.

<h3 /><h3>How to get the area of the pyramid?</h3>

On the second image, we can see that the pyramid is conformed of a square base and 3 triangles.

To get the surface area of the pyramid, we can just get the area of each of these simpler parts.

The base is a square of 22 in by 22 in, then the area of the base is:

B = (22in)*(22 in)  = 484 in^2

For each triangle, the area will be:

A = (base side)*(height)/2

A = (22in)*(14in)/2 = 154 in^2

And we have 4 of these triangles, then the total area of the pyramid will be:

total area = B + 4*A = 484in^2 + 4*(154 in^2) = 1,100 in^2

Answer:

80 cubes

Step-by-step explanation:

volume of one small cube = 1 /2 × 1 / 2 × 1 / 2

= 1 / 8cm^3

let x be the number of cubes needed

1 / 8 × x = 10

x = 10 × 8

x = 80 cubes

Help me with this equation:tan36=48/14
Zigmanuir [339]

It's difficult to spot what kind of help is needed.

There's no variable in that equation whose value needs to be found.

It appears to be simply a statement, saying that the tangent of 36 degrees
is (3 and 3/7) .

As such, it's false, since the tangent of 36 degrees is roughly 0.7265 .

What exactly is the question ?
