The picture shows a triangular island: A right triangle is shown with an acute angle equal to 50 degrees. The length of the side of the triangle opposite to the acute angle is x. The length of the side of the triangle adjacent to the acute angle is y. The length of the hypotenuse is z. Which expression shows the value of z? x sin 50° y over cos 50 degrees x cos 50° y over sin 50 degrees

Question

The picture shows a triangular island:  A right triangle is shown with an acute angle equal to 50 degrees. The length of the side of the triangle opposite to the acute angle is x. The length of the side of the triangle adjacent to the acute angle is y. The length of the hypotenuse is z.  Which expression shows the value of z?   x sin 50°   y over cos 50 degrees   x cos 50°   y over sin 50 degrees

anonymous · Answer

I think the answer is
cos 50° = y/z
z cos 50° = y
z = y/cos 50
