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°.
Answer:Area=Length x breadth
Area=12 x10 = 120in^2
Step-by-step explanation:
Answer:
It's 1, 2, 3, 4, 6, 9, 12, 18, 36.
Step-by-step explanation:
First of all the list must contain 1 and 36 so it is not the first or last choice.
Find the prime factors:
36 = 2*2*3*3
So the other factors are 2 and 3 and the products formed from these factors
which are 4, 6, 9, 12, 18.
6x -18 = 3x + 9
3x = 9 + 18
X = (9+18) divided by 3
