We have:
Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:
We clear f(x):
we simply what we can:
Thus, the correct answer is;
The answer is 48. I'm sorry I can't explain cuz it's a long process
p = total # of pages
2/5p + 32 = 310 (She read 2/5 of the book, read an addition of 32 pages, and she read a total of 310 pages.) Subtract 32 on both sides
2/5p = 278 (multiply each side by 5/2 to get p by itself)
p = 695
