How would you solve this I’m confused

Step-by-step explanation:

Notice that since segments AB and DE are parallel, then angles and must be equal since they are alternate angles in between parallel lines.

So, . We also know that , then the remaining angle () in triangle CDE must be such that added to the other two angles results in . That is:

Now, since angle D equals 10 times x, we can solve for the unknown x in the equation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
