In the figure below, triangledrw is a right triangle. find the cosecant of angle r.

Option D is correct.

cosecant of an angle R is,  

Step-by-step 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

In the given triangle DRW as show in figure;

hypotenuse sides = 13 units and

Opposite side to an angle R is 12 units;

then;

Therefore, the cosecant of an angle R is,

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
