This week in math we started to learn about Trigonometry. One of the lessons was how to find the measurement of a missing side.
Step 1- You always start with labeling the sides.
- Hypotenuse (hyp): The side across from right angle (longest side in a triangle)
- Opposite (opp): The side across reference angle
- Adjacent (adj): The non-hypotenuse side next to the angle.
ex.
Step 2- Choose a ratio. To do this you can use SOH CAH TOA.
- SOH: Sine=opp/hyp
- CAH: Cosine=adj/hyp
- TOA: Tangent=opp/adj
ex.
Step 3- Insert clues into ratio.
ex.
Step 4- Ratio. On your calculator you will press either sin ,cos , or tan depending on your question then input the degree.

Step 5- We are going to isolate the variable. Move the denominator to the other side of the = and now multiply is by answer you just got.
ex.
Step 6- Once you multiply round the decimal and make sure to put a dot on top of = to show you have rounded.
