=Interior Triangle Angle Measurements= Dylan Warren

This video does a pretty good job of explaining how the interior angles of triangles relate to one another and how that can be applied to a wide variety of problems. The guy is also pretty cool. Like ice. I mean, just look at his face in the thumbnail. media type="youtube" key="DoOSc85ZSLE" height="450" width="800" (source: http://www.youtube.com/watch?v=DoOSc85ZSLE )

The image below illustrates a very basic, common problem involving interior triangle measurements. When asked to find x, you have to understand that the total angles of the interior of a triangle must add up to equal 180 degrees.

Since you have two angle measurements, 25 and 30, you can add them together to find out that you have 55 degrees accounted for in the triangle.

So, a simple way to find x is to subtract 55 from 180, yielding 125.

Therefore, you know your answer is that angle x equals 125 degrees, thanks to the way that interior angles of triangles function. (source: Dylan Warren)
