1. DanJS

The sin of an angle is the opposite side of the triangle divided by the hypotenuse. So, To figure the sin(L), you have to figure out the lengths of sides OM and OL

2. annmeez

is it a 1:1:2 ratio?

3. DanJS

both those triangles are right triangles, you can use the pythagorean theorem on triangle MNO first, to get the length of OM

4. DanJS

3^2 + 4^2 = (OM)^2

5. annmeez

would it equal 5?

6. DanJS

yes , 3-4-5 triangle

7. annmeez

okay i think i can do it now, thank you so much!!

8. DanJS

now do the same thing on the other triangle to get side OL

9. DanJS

12^2 + 5^ 2 = (OL)^2

10. DanJS

Then from definition, $\sin(L) = \frac{ OM }{ OL }$
