We can see that a and b are parallel, and c and e are parallel, so the correct option is E.
<h3>
Which line must be parallel?</h3>
On the diagram, we can see that the angles in the third quadrant of the intersections between a and c, and the intersections between b and c, are the same angle.
Then, lines a and b must be parallel.
For the intersections with line d, we can see that this time the angle is on the fourth quadrant, so c and d are not parallel.
Finally, for line e, we can see that the known angle is on the first quadrant.
Notice that the angle on the first quadrant will be equal to the angle on the third quadrant.
So for the intersections of a and e, and b and e, on the third quadrant we have the known angle (the same one as in the intersections of a and c, and a and b).
Then c and e are parallel.
Then A and C are true.
Thus, the correct option is E.

Answer: a. 4,700 mh
Step-by-step explanation:
Assuming:
The only option that is correct is a. 4,700 mh, let's prove it with the following conversion:
Answer:
.
Step-by-step explanation:
Assume that the run of this rafter is level. Then the height of the ridge (the line with a question mark next to it in the diagram) should be perpendicular to the line marked with 
. The three labelled lines in this diagram will form a right triangle.
- The line marked as
will be the hypotenuse of this right triangle. - The line marked as
will be one of the triangle's legs. - The line representing the height of the ridge (the one with the question mark) will be the other leg of this right triangle.
Hence, the height of this ridge can be found with the Pythagorean Theorem. By the Pythagorean Theorem:
.
In this particular right triangle:
.
.
Therefore, the height of this ridge would be 
. (Note the unit.)
The surface area is just the total of material used to make the object. So, in this case the surface area is just the material used to make the whole shoe box.
In this question, it states that you have to find the unit of measure that Alec will use to find the surface area of the box.
In this case, you can choose between inches, cm, ft, or many more.
The first thing you do is find the best unit to measure the shoe box with.
Cm would probably take to long to measure the lengths, and because 1 foot equals 12 inches, some sides of the box may not be 1 foot, so ft may be a little bit big.
So the only unit in between cm and ft is inches.
Inches would probably be the best unit of measure.
Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
