Answer:
464 feet
Step-by-step explanation:
The Sine of the angle of inclination gives the increase in altitude.
This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e
Sin Ф = Opposite ÷ Hypotenuse
Sin 5° = O ÷ 5328
0·08716 = O ÷ 5328
Make O the subject and multiply every fraction by 5328
(0·08716/1 × 5328)= (O/5328 × 5328)
464·388 = O
∴ The increase in altitude is 464·388 feet
This is supposed to be to the nearest foot so we round off
464·388 becomes 464 feet
