Find the height of the triangle
Paul [167]
There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.

We'll do the sine trig. identity, as it is the most effective.

Given an angle '\alpha' in a right triangle, 'sin( \alpha )' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.

So, for this setup:
sin(20)= \frac{x}{10}

Now, we solve for x:
x=10sin(20)=3.42

So, answer is 3.4
