Answer: Choice 1) The sum of the angles A and B are supplementary to angle C
Why is this the answer? Because we'll use facts 2 through 4 to help prove the triangles similar. If fact 2 is true, then fact 3 leads to helping set up the congruent corresponding angles (either A = D or C = E). Fact 4 is true because all angles are congruent to themselves, and this fact is the other angle pair we need to prove the triangles similar.
We don't use fact 1 even though it's a true statement. The fact that A+B+C = 180 isn't really useful to compare across two triangles.
Answer:
x + 18 + 28/x
Step-by-step explanation:
You first have to factor the expression that represents the area using the AC method.
When done factoring, you should get the expression (x + 4)(x + 7).
From there you divide that by x + 7 to get the length
(x + 4)(x + 7) / x + 7 = x + 18 + 28/x.
This may not be the correct answer, but I believe this is correct.
If you wish to do it quicker, you can just divide the entire expression of the area by the expression of the length, but if you were writing it down on paper, I suggest factoring it out.
Answer:
128°
Explanation:
1 = 4 because of vertical angles are the same
4 = 5 because of alternate interior angles are the same
5 = 8 vertical angles
8 = 9 alternate interior angles
9 = 12 vertical angles
180° = 12 + 11
11 = 180° - 52°
angle 11 = 128°
