TRIGONOMETRY- SECRET CODE

Slide 3

MATH WARRIORS Your mission should you choose to accept it is to use the special trigonometry codes to solve right triangles. This message will self destruct in 32 1

Slide 4

DECODER CLUES SINE sin = opposite hypotenuse COSINE cos = adjacent hypotenuse TANGENT tan = opposite adjacent

Slide 5

WHATCHA GOT? SCT OAO HHA SONG

Slide 6

Theres a Step for that! 1.Make sure you have 90, otherwise abort the mission immediately!

Slide 7

2. Circle the angle given 30 12 x Hypo Adj 3. Now identify your other targets and label them with their code names HYPOTENUSE, ADJACENT or OPPOSITE 4. Now choose your appropriate decoder SOH CAH TOA

Slide 8

cos = adjacent hypotenuse Hypo Adj 30 12 x 4. Now choose your appropriate decoder and write down your formula 5. SUBSTITUTE! cos = adjacent hypotenuse x 12 30

Slide 9

MATH TIME M ake sure your calculator is ready to decode go to mode and change your calculator from radians to degrees cos 30 = Time to use our secret decoder, grab your calculators and click the cos button and put in 30 and hit enter..866= Oh NO! How can we get rid of that 12? *12 12* 10.39 = x

Slide 10

All right warriors, now lets do another training session together and then you can try a solo mission.

Slide 11

Find the value of x 1.Do we have 90 ? 24 x 50 2.Circle the given angle 3.Identify targets and label adj opp 4.Choose your appropriate decoder and write it down TANGENT tan = opposite adjacent

Slide 12

tan = opposite adjacent 24 x 50 adj opp Find the value of x tan = opposite adjacent 5.Substitute and math 24 x 50 1.19 = *XX* 1.19 X = 24 1.19 X = 20.16

Slide 13

Case saved for Top Agents! How to determine the ANGLE of the case. 1.Locate missing angle 2.Identify targets and label 12 ? TANGENT tan = opposite adjacent 9 opp Adj

Slide 14

3. Substitute, Use the inverse key tan -1 tan -1 = 12 9 ? 36.86 or 36.9 9 12

CONGRATULATIONS ON COMPLETEING YOUR TRAINING. NOW YOU WILL COMPLETE A SOLO MISSION. BEST OF LUCK... UNTIL NEXT TIME.
