Plz help. Find sin D , sin E , cos D , and cos E . Write each answer as a fraction in simplest form

the square root of what number? if you add that, then someone will probably answer the question.

x is the total time in minutes for the free response

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

umm you say your want to . but you do know that this is the mathematics.
