Answer: 346.4
Step-by-step explanation:
The whole triangle ABD is a 30-60-90 right triangle. In 30-60-90 triangles, the smallest side is x, the middle side is x
, and the largest side/hypotenuse is 2x.
Side AB is the smallest side and therefore x=300. Side BD is the middle side and so we can use x
and we get BD=300
=519.615
The question is asking for CD, and we know that CD can be equal to BD minus BC since that would isolate CD
Triangle ABC is also a 30-60-90 triangle but the 300 feet is the middle side in this triangle. So we can do 300=x
and divide 300 by radical 3 and get that x=173.205
Side BC is the smallest side of this triangle so it would be x and x is 173.205.
Now that we have the whole side BD and the part of it BC. We can subtract BD by BC (519.615-173.205) and we get that CD=346.4
B. The sign of the product is negative because a positive mutiplied by a negative is a negative
Answer:
The height of the tower is approximately 95.263 feet
Step-by-step explanation:
The given parameters are;
The distance from the foot of the tower where the angle of elevation is measured = 55 feet
The angle of elevation to the top of the tower from a point 55 feet from the foot of the tower, θ = 60°
Therefore, by trigonometric ratio, we have;

Therefore, we have;

The height of the tower = 55 feet × tan (60°) = 55 × √3 feet ≈ 95.263 feet.
Answer:
It's not very high
Step-by-step explanation:
The angle that the string and the ground maje, is acute, because it's smaller than a right angle. So, since it is an acute angle, it's not very high. It is about 30cm high.
