We know that
<span>If the slope of the angle from the vertex is positive, then it is an angle of elevation.</span>
<span>If the slope of the angle from the vertex is negative, then it is an angle of depression.</span>
The angle of elevation is congruent to the angle of depression because they are alternate interior angles
in the picture
∠ 1 is the angle of elevation from submarine to the boat
∠2 is the angle of depression from boat to submarine
∠3 is the angle of elevation from boat to the lighthouse
∠4.is the angle of depression from the lighthouse to the boat
therefore
the answer is
∠2 is the angle of depression from boat to submarine
Answer:
16.65 cups
Step-by-step explanation:
Step one:
height =12 cm, and
the base has a radius =5.5 cm
Volume of the cup = πr^2h
substitute we have
volume= 3.142*5.5^2*12
volume= 3.142*30.25*12
volume=1140.546cm^3
Step two:
volume of cooler= 18,997 cm^3
hence the number of cups to fill it is
=18,997/1140.546
=16.65 cups
