Step-by-step explanation:
11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.
12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.
13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.
14. Lines perpendicular to the same line are parallel.
Multiply $43.85 by .05, take that add to original price and get $46.04. Next take $46.04 multiply that by .15, you will get $6.90. Then add it to $46.06 and get $52.94, divide by 4 and you will pay $13.24.
Explanation:
This might not be how you are supposed to do it but,
We can see the two triangles are similar because AA similarity.
We know that the sides are proportional so we can make:

We get,

Because sides can't be negative, x = 2/3
