Homework: Study for your quiz tomorrow (3/1). Finish your quiz review. Also finish all problems on pages 23 and 49 in your Unit 3 packet. Your Unit 3 test will be next Friday, 3/8.
Tuesday, 2/26: Today in class we learned how to find a side length in a right triangle given one side length and one acute angle measure. Below is a video explaining the notes we took in class today on pages 15, 16 & 17 in your Unit 3 Right Triangles packet. Homework is to complete pages 18 & 19. If you don't have a calculator at home, there is a great scientific calculator on www.desmos.com (just click on the scientific calculator). For your homework, LABEL your sides (H, A and O), then set up your equation with the correct trig function and solve. You MUST show your work.
Notes for pages 15, 16 & 17:
Directions for Monday, 2/25: You should all have the page of instructions for today that I left with the sub. You will need your Unit 3 packet and a calculator (no cellphones allowed). Student helpers will sign out a calculator to you if you need to borrow one for class. Please use the headphones provided to listen to the videos to fill out your notes and then complete your classwork. Whatever you don't finish for classwork is your homework. The following should be finished before class on Tuesday: notes filled out on pages 1, 2, 7 & 9 and classwork/homework: ALL of pages 3, 8 & 14. If you need to finish your Unit 2B test, you can finish during AO on Tuesday 2/25 or after school during tutoring.
