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.
3.
2. Find the length of x.
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.

So are we gonna get some steps for this or what????
Steps:
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.
