A little pick-me-up

DO NOW: Work silently and independently on the following problems for 4 minutes. It’s OK if you don’t get all the right answers, but make sure you do your best 1. Find the length of x. 2. Find the length of x. 3.

MEME OF THE DAY

Right Triangle Trigonometry

VOCABULARY: Adjacent side: The side next to an acute angle in a right triangle that is not the hypotenuse Opposite side The side across from an angle Hypotenuse: The side opposite from the right(90 degree) angle; the longest side

Ex. 1: Label the opposite, adjacent, and hypotenuse for the triangle below

Ex. 1: Label the opposite, adjacent, and hypotenuse for the triangle below

Additional Practice Try the next 6 problems with a partner. You will be given 8 minutes to complete all 6 problems and then we will review them as a class.

THINK SOH CAH TOA SIN= OPPOSITE HYPOTENUSE COS= ADJACENT TAN= OPPOSITE

hypotenuse hypotenuse opposite opposite adjacent adjacent

So are we gonna get some steps for this or what???? Step 1: Identify the angle you are given Step 2: Identify all the sides in reference to that angle. (ex: opposite sides, adjacent sides, hypotenuse) Step 3: Using the 2 sides or 1 side and an angle, you are given, choose whether you are using sine, cosine, or tangent. Step 4: Set up your equation. Step 5: Solve for your missing side or angle.

Ex. 1: Write the ratios for sin D, cos D, and tan D

Ex. 2: Write the ratios for sin Z, tan Z, and cos Z

Your Turn! Work with your group members to complete the next 6 problems. When you are done, double check your answers and wait quietly until we review as a class. Make sure you are working quietly and efficiently!

LET’S KEEP GOING! Practice: Write the ratios for sin M, cos M, and tan M.
