This is probably wrong, but from what I know, there are 16 vertices, 24 edges, and 10 faces. I’m not sure if this is wrong, but I did some math and some research, and this is what I got.

∠1 ​ and ∠2 are supplementary. ∠1=124°∠2=(2x+4)° Select from the drop down menu to correctly answer the question.

Remark
Supplementary angles add up to 180o. 

Givens
<1 = 124
<2 = 2x + 4

I imagine you are looking for either x or <2. 

Equation
<1 + <2 = 180          Substitute the givens
124 + 2x + 4 = 180  Collect like terms on the left.
128 + 2x = 180         Subtract 128 from both sides
2x = 180 - 128          Collect like terms on the right   
2x = 52                     divide by 2
x = 52/2
x = 26 <<<<<<<<< answer

<1 = 124
<2 = 2x + 4 = 2*26 + 4
<2 = 52 + 4
<2 = 56  <<<<<<<< answer

We need choices if you want an exact answer.

Question:

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. what is the unit rate at which Martian paints in walls per gallon

Answer:

0.78125  walls per gallon

<em></em>

Step-by-step explanation:

Given

Paint = \frac{5}{8}\ gallon

Wall = \frac{4}{5}

Required

Determine the unit rate

This is calculated as:

Unit\ Rate = \frac{Wall}{Paint}

Substitute values for wall and paint

Unit\ Rate = \frac{5/8}{4/5}

Simplify:

Unit\ Rate = \frac{5}{8}/\frac{4}{5}

Change to *

Unit\ Rate = \frac{5}{8}*\frac{5}{4}

Unit\ Rate = \frac{5*5}{8*4}

Unit\ Rate = \frac{25}{32}

Unit\ Rate = 0.78125

<em>Hence, the unit rate is: 0.78125  walls per gallon</em>
