Question

solve Q4 , Q5 , and Q6

Two hunters, Paul, P, and Richard, R, are sitting in tree stands 200 yards apart, If Paul spots a deer D, at an angle RPD = 30 degree and Richard spots the same deer at an angle PRD= 42degree, how far is the deer from Paul?._________From Richard?___________ In order to determine the distance between two aircraft, a tracking station continuously determines the distance to each aircraft and the angle alpha between them. Determine the distance between the planes when a = 25 degree, b = 69 miles, and c = 36 miles. A man that is 6 feet tall casts a shadow 9, 5 feet long. Find the angle of elevation of the sun. Show the calculation used.

Explanation / Answer

4) PR = 200 yard ; P = 30 deg; R = 42 deg

PD = ? ; RD= ?

D = 180 - 30 -42 = 108 deg

APPLY SINE RULE : PD/SINR = PR/SIND

PD = SIN42*200/SIN108 =140.71 yards

Now , RD/SINP = 200/SIN108

RD = 105.15 YARDS
