Jennifer stands 80 ft above sea level at the top of a lighthouse. she sees a boat sailing 400 ft from the lighthouse. what is the angle of depression from the top of the lighthouse to the boat? round to the nearest whole degree.

Let 

 A = the angle of depression 

Y= the distance of the boat from the lighthouse= 400 ft

 tan A=X/Y > 80/400=0.2

arctan (0.2)=11.31 degree

 The answer is the angle of depression is 11 degree

1/5x+9 2/5y+7

step-by-step explanation:

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
