Question

Ben is measuring the height of a cliff from a point S on the ground, as shown below.



What is the height, in meters, of the cliff?



77 tan 50˚



77 sin 50˚

Answer 1

77 over tan 50 ..
77 over cos 50

Answer 2

77 tan 50 i think...sin/cos=tangent,,right?

Answer 3

im not even sure i dont understand the tan cos and tan..

Answer 4

sin(θ)/cos(θ) = tan(θ)
This is always true, on and off the unit circle

but the sin cos and tan functions must have the same parameter within them

i.e.
sin(a+b+c^2)/cos(a+b+c^2) = tan(a+b+c^2)

But
sin(a)/cos(b) does not equal tan(??)

this is what yahoo said..

Answer 5

ah,,i know now,it's cosine

Answer 6

so it would be 77 over cos 50?

Answer 7

cosine = (adjacent side) / hypotenuse,,,

Answer 8

yes indeed..
