Answer:
Correct answer: Db = 411 .18 ft
Step-by-step explanation:
Given:
α = 27° angle of depression
Dt = 462 ft distance from the top of lighthouse to the boat
Db = ? distance from the base of the lighthouse to the boat
Here we have a right triangle with hypotenuse Dt and one leg Db.
By definition
cos α = Db / Dt ⇒ Db = Dt · cos α
Db = 462 · cos 27° = 462 · 0.89 = 411 .18 ft
Db = 411 .18 ft

Answer:
£156.24
Step-by-step explanation:
Ben worked for 12 hours.
Total = Normal working hours + overtime working hours
12 hours = 9 hours + 3 hours
Ben is paid £12.40 per hour(normal working hours)
he is paid overtime for the additional hours at a rate of 1.2 times his normal rate of pay.
Amount earned Overtime = 1.2 × £12.40
= £14.88
Total amount earned for 12 hours of work = 9(£12.40) + 3(£14.88)
= £111.60 + £44.64
= £156.24
Total amount earned for 12 hours of work = £156.24
