This week of math we learned the basics of trigonometry. We learned how to calculate missing sides and angles through the acronym SOH CAH TOA. Trigonometry is new type of math that I’ve never dealt with. At first I thought the whole concept was confusing and hard, but as I practiced more, I’ve grown to really like solving trigonometry equations. 🙂

**1st equation**: First, label all the sides of the triangle to make it easier to read, and base this of the reference angle. (Adjacent, Opposite, Hypotenuse) Second, take the side that is asked to find and the side with the given length. Which will help you choose which sign to use. **Third, get the variable on the top of the fraction (in this case 12) to balance the equation, and then isolate the variable and multiply both numerators by the denominator of the fraction that contains the variable**.** **Lastly, solve the equation.

**2nd equation**: First, label all the sides of the triangle to make it easier to read, and base this of the reference angle. (Adjacent, Opposite, Hypotenuse) Second, take the side that is asked to find and the side with the given length. Which will help you choose which sign to use. **Third, to find the angle you would have to multiply the sign on both sides, but it changes into a negative when it moves to the** **other side of the equation (invert)**. Lastly, solve the equation.

**3rd equation**: First, label all the sides of the triangle to make it easier to read, and base this of the reference angle. (Adjacent, Opposite, Hypotenuse) Second, take the side that is asked to find and the side with the given length. Which will help you choose which sign to use. **Third, eliminate 24 by multiplying it to both sides of the equation**. Lastly, solve the equation.
