Answer:

sin Ф=3/√13

Cos Ф=2/√13

Tan Ф=3/2

Step-by-step explanation:

Let x=2

Let y=3

Let r be the length of line segment drawn from origin to the point

[tex]r=\sqrt{x^2+y^2}[/tex]

Find r

[tex]r=\sqrt{2^2+3^2} =\sqrt{4+9} =\sqrt{13}[/tex]

Apply the relationship for sine, cosine and tan of Ф where

r=hypotenuse

Sine Ф=length of opposite side÷hypotenuse

Sin Ф=O/H where o=3, hypotenuse =√13

sin Ф=3/√13

CosineФ=length of adjacent side÷hypotenuse

Cos Ф=A/H

Cos Ф=2/√13

Tan Ф=opposite length÷adjacent length

TanФ=O/A

Tan Ф=3/2
