Determine whether the triangles are similar. If so, name the postulate or
theorem you used.

Yes, AA~

Step-by-step explanation:

because 2 of the angles are the same (90 and 52) they have to be the same. The triangle on the right is known to be 90 degrees because 52+38 is 90 and 180-90 is 90 and a triangle has to add up to 180 degrees

400 - 15x < 300

Step-by-step explanation:

We are told that she has 400$ in her bank account.

Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.

Total total withdrawal each week = 10 + 5 = $15

If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.

Thus, amount left after x number of weeks is:

400 - 15x

We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.

Thus;

400 - 15x < 300
