Question

Find the value of cos θ for the angle shown.

Answer 1

We're missing the drawing!

Answer 2

Is it involved with Vectors ?

Answer 3

\[Cos \theta= B/H\]

Answer 4

how do i solve for the answer

Answer 5

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...

Answer 6

so its cos θ = 4/7

Answer 7

Yup!
