Again, it should be stressed that trigonometry will not be needed on the SAT math section. When it appears that trig is needed, they may be trying to trick the person taking the test. Usually, the Pythagorean Theorem will work for these types of problems. Having said that, there are times when trig may come in handy on the SAT for getting answers more quickly. So, for those familiar with trigonometry should use it if it can help.
