Calculate the length a to two decimal places.

If 90° < θ < 180° and cotθ = -1/3, then cscθ =

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
