Answer 2

we have a right triangle, so we can say

cos(50) = y/z

and

sin(50) = x/z


solve for z in each case

Answer 3

how do i solve for Z

Answer 4

say you have

a = k/z

------------------

a = k/z

az = k

z = k/a

Answer 5

z=y sec(50 degrees)

Answer 6

so it would be the first option?

Answer 7

cos(50) = y/z

z*cos(50) = y

z = y/cos(50)

Answer 8

so y over cos 50

Answer 9

yes
