Someone help please this is for trigonometry
Softa [21]
Hi there!

Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.

Anyways,

tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75

cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78

For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...

angleC=180-(90+50)
angleC=180-140
angleC=40°

The volume of the square base pyramid is 588 ft³

The Volume of the rectangular prism is 120 ft³

The Volume of a rectangular pyramid is 360 ft³

<h3>What is volume of a shape?</h3>

Volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.

Volume of a square base pyramid = 1 / 3 × B × h

where

B = base area

Therefore,

Volume of a square base pyramid = 1 / 3 × 7² × 12

Volume of a square base pyramid = 1764 / 3 = 588 ft³

Volume of a rectangular prism = lwh

Volume of a rectangular prism =  6 × 5 × 4 = 120 ft³

Volume of a rectangular pyramid = 1 / 3 lwh

Volume of a rectangular pyramid = 1 / 3 × 10 × 12 × 9 = 1080 / 3 = 360 ft³

Trash Cans: Elliot's family has a cylinder shaped trash can. It takes the family a few days to fill the trash can up. Elliot wan
atroni [7]

Answer:

4696.0 in.^3

Step-by-step explanation:

The trash can has a cylinder shape, so we have to calculate the volume of a cylinder.

The volume of a cylinder is given by the formula

V=\pi r^2 h

where

V is the volume

r is the radius of the base

h is the height of the cylinder

In this problem, we have:

h = 24.90 in. is the height of the can

d = 15.50 in. is the diameter of the can, so the radius is half of this value:

r=\frac{d}{2}=\frac{15.50}{2}=7.75 in.

Therefore, the volume of the trash can is:

V=\pi (7.75)^2 (24.90)=4696.0 in.^3
