1. 37° x 3 y Find x and y using Trig Ratios

2. How do we use trig ratios to solve for missing sides and angles in right triangles? AGENDA: WARMUP – GO OVER HOMEWORK EXAMPLES FINDING ANGLES MORE TRIG PRACTICE CORE 1 Monday(TRIG WORD PROBLEM) RIGHT TRIANGLES TEST Tuesday

3. Type 2 Ex. 1 – Find angle measures. y°y° x°x° 12 13 First use Pythagorean Theorem to find the missing side length. 5 x = 67.38y = 22.62 Check: 67.38 + 22.62 + 90 = 180

4. Type 2 Ex. 2– Find angle measures. x 5 3 4 c = 5 y Check: 36.87 + 53.13 + 90 = 180

5. Type 2 Ex. 3– Find angle measures. 12 x y Check: 30 + 60 + 90 = 180

6. A 20-foot ladder is leaning against the side of a house. If the ladder is 8 feet from the base of the building, calculate the angle of elevation the ladder forms with the ground x 8 20
