Question

The picture shows a triangular island.



Which expression shows the value of z?
Answer
x cos 50°
x sin 50°

Answer 1

cos 50 = y/z
sin 50 = x/z
so rearrange these to give z =

Answer 2

z = y / cos 50
also
z = x / sin 50

so none of the options is correct
are you sure you have got the question right?

Answer 3

@Jimmyrep is correct.\[z=x \text{ Csc}[50{}^{\circ}] \]

Answer 4

oh yes - because csc = 1 / sin

Answer 5

also x = z sin 50 - maybe the z and x should be reversed in the question?

Answer 6

which do you think is the best answer

Answer 7

i dont really know - probably z = csc 50
