Question

In the figure below, triangleDRW is a right triangle. Find the cosecant of angle R.

Answer 1

Option D is correct.

cosecant of an angle R is,
`(13)/(12)`

Explanation:

In the given triangle DRW is right triangle.

To find the cosecant of angle R;

In a right angled triangle, the cosecant of an angle defined as

the length of hypotenuse side divided by the length of the side opposite the angle.

The abbreviation for cosecant is csc

i,e

`csc= (Hypotenuse Side)/(Opposite side)`

In the given triangle DRW as show in figure;

hypotenuse sides = 13 units and

Opposite side to an angle R is 12 units;

then;

`csc R = (13)/(12)`

Therefore, the cosecant of an angle R is,
`(13)/(12)`
