Answer:
A
Step-by-step explanation:

Using Pythagoras' Theorem a² + b² = c² to find the side opposite the angle:
⇒ 5² + b² = 13²
⇒ b² = 144
⇒ b = 12
⇒ opposite side = 12


Therefore, the common quadrant is quadrant IV and

Answer:
A
Step-by-step explanation:
Since cosine is positive and sine is negative that puts θ in Quad IV.
From right triangles we know:
Cos θ = adjacent/hypotenuse = 5/13
sin θ = opposite/hypotenuse = ?/13
To find the opposite side across from θ use the pythagorean theorem.
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
we are given that sin is < 0 so sinθ = -12/13
