Can you guys help me fill the right angle measures

Veseljchak [2.6K]

Answer:

if ∠2 = 160° then ∠8 = ∠2 and ∠3 = 360° - 160° and ∠5 = ∠3

SO BASICALLY,

∠2 = 160°

∠3 = 200°

∠5 = 200°

∠8 = 160°

keep in mind though that this depends on the angle measure of ∠2

ok bye

Each cube in this rectangular prism is 1 cm3.What is the volume of the rectangular prism?

Lelechka [254]

Answer:

Volume of rectangular prism = $20\ cm^3$

Step-by-step explanation:

Given rectangular prism is made up of small cubes of volume 1 cubic centimeter.

To find volume of rectangular prism.

Solution:

Volume of rectangular prism is = $length\times width \times height$

We know that all sides of a cube are equal in measure.

So, we will count the number of cubes on each side to get the exact measure.

Length side = 4 cubes = 5 cm

Width side = 2 cubes = 2 cm

Height side = 2 cubes = 2 cm

Thus volume of rectangular prism = $5\ cm\times 2\ cm \times 2\ cm$

Volume of rectangular prism = $20\ cm^3$
