2 answers:
Answer:
x = 17
y = 17
Step-by-step explanation:
You would need to use the following trigonometric functions cosine and sin. Sin is used for the y-variable to get the answer and cosine is used for the x-variable to get the answer. For this case, you would need to do 34 sin 30 for y and 34 cos 30 for x. You should get 17 for y and 17 root 3 for x when you put it in the calculator.

Answer: Yes, she will finish before winter break is over.
Explanation:
Since we have given that
Number of days in winter break = 17
Number of pages she read in each day = 75
Number of pages in the Harry Potter series she wants to read = 759
Now, we'll use unitary method,
in 1 day , she read = 75 pages
in 17 days , she read is given by
and 759 pages is less than 1275 pages.
So, she will finish before winter break is over.
