Section 9-1

For these problems to be worked in 9-1, you have to know SOHCAHTOA. This stands for:
Sin= opposite/hypotenuse Cos= adjacent/hypotenuse Tan= opposite/adjacent

To solve a problem, you simply draw your right triangle and add in the degrees that they give you. Once you are done, you look to see what they are asking you to solve, and you look for the appropriate formula. Then you are done. If you can remember SOHCAHTOA, you can remember all the formulas because secant, cosecant, and cotangent are all reciprocals of these.

Opposite is the degrees that is across from the one that is already given to you. Adjacent is the degrees that is attached to the one already given, and hypotenuse is always the degrees across from the right angle.

Solve the triangle ABC.
Angle B- 34degrees Angle b- 26 degrees Angle A- 90 degrees
Those are the angles given, so you need to find angles a, C, and c.
