This week I learned how to label the sides of a triangle and to find the angles using trigonometry. Using SOH CAH TOA you can find these all without using Pythagorean theorem. A challenge can be correctly labeling the Adj., Opp., and the Hyp. Another one is getting the wrong formula SOH CAH TOA. And another challenge is not doing the right calculations on a calculator. This is applied when you are finding the sides or angles of a triangle.

For this example I’ll show how to find X(Hyp.) and angle A and angle B.

 

For this you really need to label it correctly on what angle you want to find. First Angle A.

 

 

 

Then Angle B..

With these angles you can now find X(Hyp). As long as don’t use Tan. again you will get the same answer. Also as long as you use the formula correctly.
