Answer:
29.7°
Step-by-step explanation:
In a right triangle representing the geometry of the problem, the side opposite the angle is the height of your observation (400 ft). The side adjacent to the angle is the distance from shore (700 ft).
You know the tangent ratio is ...
Tan = Opposite/Adjacent
so your angle of depression satisfies ...
tan(angle of depression) = (400 ft)/(700 ft)
Using the inverse function, we find ...
angle of depression = arctan(4/7) ≈ 29.745°
The angle of depression is about 29.7°.
180 cm^3
A=lw
A=20×9
A=180
334.65 just multply 345*0.97
Just subtract a tuig from the thung
Heres an example
subtract 7 from 12 an you will get 5 for number 1 do that for the rest
B, $432 per 24 hours
