What is r = q equal to?

A)sin xº
B)cos y°
C)Cos xº
D)tan yº

Given:

The figure of a right angle triangle.

To find:

The value which is equal to r÷q.

Solution:

In the given right triangle, the length of the hypotenuse is q units.

For angle x degrees, perpendicular is p units and base is r units.

For angle y degrees, perpendicular is r units and base is p units.

In a right angle triangle,

So,

Therefore, the value of r÷q is equal to siny or cosx. So, the correct option is C.
