How do I represent a function in tables

What function is there supposed to be a picture

When both the independent quantity (input) and the dependent quantity (output) are real numbers, a function can be represented by a coordinate graph. The independent value is plotted on the x-axis and the dependent value is plotted on the y-axis.

To answer this, you must first know what SohCahToa is:

Sin - opposite over hypotenuse

Cosine - Adjacent over hypotenuse

Tangent - Opposite over adjacent

In this situation, you need to use Tangent since the 8 is opposite from the X and the 10 is adjacent. So now calculate using the inverse of tan to find the angle. Tan^-1 (8/10)

Answer is 38.7 degrees
