Question

find x. (PICTURE INCLUDED)

PLEASE HELP!

Answer 1

Use your angle formula. What do you know about cos, sin, tan?

Answer 2

i know how to find it if there is a degree. but i suck at finding cos, sin, or tan with a variable. get me?

Answer 3

so is it true to say

sin(x)=10/14 ?

Answer 4

yes. so all i would do is divide 10 by 14?

Answer 5

that is what sin(x) would be. Not x by its'self.

Answer 6

how do you get x by itself? the question says find x rounded to the nearest whole degree.

Answer 7

so we take the inverse of sin to find x.

so since

sin(x)=5/7 just simplified 10/14

then x=arcsin(5/7) which is the
