We're missing the drawing!

Is it involved with Vectors ?

$Cos \theta= B/H$

5. miley23

how do i solve for the answer

6. BluFoot

This is how I would do it. cos(ø) = cos(-ø) So the cos of the smaller angle in the clockwise direction is the same as the big angle in the counterclockwise direction. cos = adjacent / hypotenuse adjacent = 4 and hypotenuse you can find through pythagorus. There's probably an easier way...

7. miley23

so its cos θ = 4/7

8. BluFoot

Yup!
