only: questions 10, 11 ,12

10. 4) 62°

11. 1) 100° 2) 80° 3) 100°

12. 1) 47° 2) 133° 3) 47°

Step-by-step explanation:

10. since 118° and angle 4 are on a straight line they would equal to 180° so you do 180-118 to get angle 4

11. angle 2 is the same as the angle that's 80° to get angle 3 you subtract 80 from 180 and that's the same as angle 1

12. angle 2 is the same as the angle that's 133° and since angle 1 and 3 are the same you just subtract 133 from 180 to equal those 2 angles

the answer should be a. snail

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
