Given sin

Effectus [21]

Answer: $\frac{11}{12}$

Step-by-step explanation:

Use trigonometry (shown in image below) to find the 3 side-lengths:

The side opposite of θ = $\sqrt{23}$
The base side adjacent to θ = 11
The hypotenuse = 12

According to right triangle trigonometry:

cos θ = $\frac{adjacent}{hypotenuse}$

Substitute in the values:

cos θ = $\frac{11}{12}$
