Answer:
8.4cm
Step-by-step explanation:
We can start by taking a look at the problem, and noting that we have on side of a right triangle and need the second side; not that we will not need to interact with the hypotenuse. This lets us know to use the trigonometric function tangent.
The tangent function (from this point foward 'tan') is defined as opposite/adjacent.
First, taking a look at the angle, we can write the formula tan(35) = x/12
Next, we can cross multiply and get 12(tan(35)) = x
Then, we can use a calculator and calculate than x = 8.4cm
I hope this explanation is in-depth enough and that it helps you to learn this material! Good luck on your trigonometric trail!
