Answer 2

Is this correct setup? So I did tan 25 degree= 12/x

Answer 3

i agree

Answer 4

x-5.59? do i take the inverse?

Answer 5

no

Answer 6

you take the inverse when you already have the value and you want the angle

Answer 7

ohh k so is my answer correct? im still not used to of the calculator with the tangent stuff so please check

Answer 8

to solve for x
12/x = tan 25
x = 12/tan 25 = 12/ 0.466 = 25.75
