3/23 Bell Ringer Find the three trig ratios for angle G: sin(G) = ?? cos(G) =?? tan(G) = ?? Θ Homework: Finish today’s IP and STUDY FOR RE-TAKE TOMORROW ON UNIT 8!!
News and Notes • Perfection Award: 1st (Great work) and 4th (Great work and perfect Exit!) • ACT Workshop today after school in Rm 218 • When is the test retake? • End of Perfection = 4/31
How should I prepare for tomorrow’s retake? • Re-do the entire test on your own. Use your corrections from the day after to help! • Be comfortable with Distance and Midpoint Formula • Go over all old Pythagorean Theorem problems.
3/2 Agenda • I CAN use trig ratios to find missing sides of a right triangle when given one angle and one side. • 1. Intro to New Material • 2. Guided Practice • 3. Independent Practice • 4. ACT Question of the Day
New Material – Example 1 • Solve for x: • Know: Angle = 75° Hypotenuse = 30 • Want to Know: Adjacent • What trig ratio? Cos = adj / hyp
y New Material #2 55° x 10 • Know: Angle = 55° and opp side = 10 • Want to Know: Adj.Hyp.
How old is Mr. Chrischilles? • The answer to this question is my age B 48 30°
Independent Practice • You now have the rest of class to work on the independent practice on the back of today’s guided notes. • IF YOU DO NOT HAVE A CALCULATOR go through the process until you get to the last step; at this point just write what you would plug into your calculator!
Exit ACT Question of the Day Which of the following shows how to solve for y? A. B. C. D. Homework: Finish Independent Practice and study for Unit 8 RETAKE!!!
