1. Do Now… 1) Use SOH-CAH-TOA to find the length of side b. 1) Miniature Joe walks 4 cm North and then heads 3 cm West. Draw a diagram (to scale) of his trip and measure the distance between his initial and final position. 51° 7.0 km b = ? N S E W

2. Do Now… 1) Use SOH-CAH-TOA to find the length of side b. What do we know? 51°7.0 km b = ?

3. Do Now… 1) 2) Miniature Joe walks 4 cm North and then heads 3 cm West. Draw a diagram (to scale) of his trip and measure the distance between his initial and final position. 4 cm North 3 cm West N S E W

4. Hypotenuse represents the resultant vector. O Sum of two or more vectors. O What is the magnitude of the resultant vector? In which direction is it pointing? 4 cm North 3 cm West N S E W

5. What is the magnitude and direction of the resultant vector? O Magnitude: We can calculate or measure the length of the resultant vector. O Direction: What is the angle θ between the resultant vector and the North direction? N S E W 4 cm North 3 cm West θ 5 cm ?

6. Direction: What is the angle θ between the resultant vector and the North direction? We know… N S E W 4 cm North 3 cm West θ 5 cm ? West of North
