Answer:First you have to know which sideS mach. Put the longest side of the first triangle over X (which is the longest side of the second triangle), then equals to any side of the first triangle over the equivalent side of the second triangle, for example 20/x = 12/18. And after that you can multiply in X form. 12x = 360

X=30
