The bottom of Ignacio's desktop is 74.5 cm from the floor. Ignacio sits in his adjustable chair, and the tops of his
legs are 49.3 cm from the floor. Each clockwise rotation of the knob on the chair raises Ignacio's legs by
4.8 cm.
MY
TATUS
Write an inequality to determine the number of clockwise rotations, r, Ignacio could make with the knob
without his legs touching the desk.
MY
What is the solution set of the inequality?

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
