Answer:The answer to your question is below

Step-by-step explanation:DataA (4 , -3)

r = ?

sin = ?

cos = ?

tan = ?

Process1.- Plot the pointThis point is in the fourth quadrangle

2.- Calculate rWe have the Opposite side and the Adjacent side

tan Ф = -3/4

tan⁻¹ Ф = Ф = 323.1

Ф = 323.1°

3.- sinФ =Calculate the hypotenuse

c² = 4² + (-3)²

c² = 16 + 9

c² = 25

c = 5

sinФ = -3/5cos Ф = 4/5tan Ф = -3/4
