A hot air balloon is flying at and altitude of 2101 feet. If the angle of depression from the pilot in the balloon to a house on

alekssr [168]

The problem is modelled as right angle triangle, shown in the diagram below

The distance between the pilot and the house is labelled as $x$

Using the trigonometry ratio of sine
$sin(31)= \frac{opposite}{hypotenuse}$
$sin(31)= \frac{2010}{x}$
$x= \frac{2101}{sin(31)} = 4079.3 ft$

David can finish painting the room in six hours and his elder brother Anthony can finish it in four hours if both brothers paint

lbvjy [14]

Answer:

2.4 hours

Step-by-step explanation:

David's time = 6 hours

Anthony's time = 4 hours

the combined time is given by the following formula

1/ (david's time) + 1/(anthony's time) = 1/total time

1/6 + 1/4 = 1/Total

4/24 + 6/24 = 1/Total

10/24 = 1/ total (taking reciprocal of both sides)

24/10 = total

total time = 24/10 = 2.4 hours
