Ineed an answer and explanation ? very much appreciated! < 3

Step-by-step explanation:

You need to know angles like PQT and the one labeled 148 equal 180, since putting them together makes a straight line and the relationship between "alternate exterior" and "alternate interior" angles.  Basically they are the same

If you need a more in depth explanation on those angles let me know.

ANyway, we'll start with what I mentions at first;

PQT = 180 - 148 = 32

Then PQT and SRT are alternate  interior angles so they are equal

RST = 180 - 104 = 76

then RST and TPQ are also alternate interior angles so both equal 76

Now, the sum of angles in a triangle are 180 so TPQ + PQT + QTP = 180 and RST + SRT + RTS = 180.  Plugging in what we know gets us RTS = 180 - 108 = 72 = QTP.

You might be wondering how this helps, well, RTQ is a straight line, so PTR + QTP = 180.  So that means PTR = 180 - QTP = 180 - 72 = 108

Let me know if something here doesn't make sense.  

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
