This week in precalc 11 we learned about sine law. I chose this topic to cover for this week because you can use sine law for any type of triangle (acute, obtuse, right, non-right etc.) you can also use this formula to find angles AND sides. 

If you would like to find an angle, have SIN be on top. If you want to find a side flip it the other way (small letter goes on top)

• once you have the formula fill it out with the given information.
• Sin A, B, C are the angles
• a, b, c are the sides
• Select one of the ratios from the law of sines based on the given parts of the triangle.
• Use the chosen ratio to set up an equation involving the known and unknown parts of the triangle.
• isolate and solve.
• make sure to add brackets when putting the numbers in the calculator.
