  2. EOCT Week 13 #2

  3. Homework Answers

  4. What did the student do wrong? Find x 2x=5 x =5/2 45˚ 5 x 45˚

  5. What did the student do wrong? Find x 49 + 64=c² 113=c² √113=c 8 7 x

  6. Trig Ratios

  7. What are the three Trig Functions? SINE COSINE TANGENT

  8. What Represents an unknown angle? Greek Letter q

  9. C 5 2 A M Trig Ratios

  10. Finding a side.(Figuring out which ratio to use and getting to use a trig button.)

  11. Finding a side Which sides do you have? (given angle is your theta ) What number did they give you in comparison to the number you need to find? Set it up. Solve for the variable.

  12. is a leg. You are given AC, which is the opposite side to given angle, B. Since the opposite side and adjacent side are involved, use a tangent ratio. Just Watch Find the length of BC. Round to the nearest hundredth. ?

  13. Write a trigonometric ratio. Substitute the given values. Multiply both sides by BC and divide by tan 18°. BC 36.93 ft Simplify the expression.

  14. 20 m 20 55 ) tan x #1 Try together! Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  15. 80 ft 80  ( 72 = ) ) tan x #2 Try together! Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  16. 283 m x #3 You Try! Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  17. #4 You Try! 20 ft x

  18. Additional Practice
