  4. CCGPS Geometry UNIT QUESTION: What patterns can I find in right triangles? Standard: MCC9-12.G.SRT.6-8 Today’s Question: How do we use trig ratios to find the missing sides and angles of a triangle? Standard: MCC9-12.G.SRT.6-8

  5. Finding an angle.(Figuring out which ratio to use and an inverse trig button.)

  6. 20 m ) 20 / 40 Tan-1 40 m Ex: 1 Figure out which ratio to use. Find x. Round to the nearest tenth. x Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  7. 50 m 15 m ) 15 / 50 Sin-1 Ex: 2 Figure out which ratio to use. Find x. Round to the nearest tenth. x Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  8. Ex. 3: Find . Round to the nearest degree. 17.2 9

  9. Ex. 4: Find . Round to the nearest degree. 7 23

  10. Ex. 5: Find . Round to the nearest degree. 200 400

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

  12. 20 m 20 55 ) tan x Ex: 6 Figure out which ratio to use. Find x. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  13. 80 ft 80  ( 72 = ) ) tan x Ex: 7 Find the missing side. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  14. 283 m x Ex: 8 Find the missing side. Round to the nearest tenth. Shrink yourself down and stand where the angle is. Now, figure out which trig ratio you have and set up the problem.

  15. Ex: 9 Find the missing side. Round to the nearest tenth. 20 ft x

  16. When we are trying to find a side we use sin, cos, or tan. When we are trying to find an angle we use (INVERSE) sin-1, cos-1,ortan-1.
