Explanation:
It's always best for these types of questions to visualise it. A right triangle has base angle of 90°. Mark in what you know, and leave out the rest. Notice how the question doesn't ask for a hypotenuse. This means that you might be using the tangent function as the tangent function also doesn't require a hypotenuse.
So now, you have a side of 12cm, with the corresponding 39° angle marked.
To find the missing length, you can use the tangent function to approximate the length:
(opposite/adjacent)
Now, isolate the variable, x:

Answer:
The slope is -5/7
Step-by-step explanation:
Slope is rise / run. In other words, the change in y / change in x:
