There are three possible results when a plan intersects with a three-dimensional figure and these are:

Answer:

208 feet

Step-by-step explanation:

We have to multiply 4x4 to get 16, and since there looks like there are 5 small squares we multiply 5x16 to get 80. And then there are 2 bigger squares that are 8x8 to get 64, then we multiply by 2 to get 128, then we add 80 (the sum of the 5 smaller squares) to get to a total of 208.

Can anyone help me, i will give brainiest.

Answer: ∠DOB: 48°

Step-by-step explanation:

1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°

2. now we can solve for the missing variable, n.

108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°

3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°

hope this heped! ♡
