2. The angle of depression of the top and bottom of a tower as seen from the top of a 100m high cliff are 300 and 600 respectively. Find the height of the tower.?

From the top of a lookout tower, a ranger spots a forest fire at a 30° angle of depression and the near end of the fire at a 40° angle of depression. The tower is 105 feet tall.Do you have enough information to find the length of the forest fire?
yes
A guy wire is attached to a tower at a point on the tower 115m from the base The guy wire is anchored to the ground at a point on the ground 24m from the base of the tower Draw the diagram?
I'm unable to draw diagrams. However, you can visualize the scenario with the tower standing vertically. One side of the triangle represents the tower (115m) and the other side the anchor point on the ground (24m). The guy wire forms the hypotenuse of the right triangle. The angle between the tower and the ground is formed by the guy wire.
An air traffic controller estimates the angle of elevation from the control tower to an approaching airplane as 29°. The ground distance from the tower to the airplane is 4 miles?
Missing information. If you drew a right triangle with the airplane at the top of the short side, the base would be the 4 miles on the ground. That angle would be the 29 degree angle. So what are you looking for?
What is a real life example of right angle?
The slant which lies between the ground and the slope of the Leaning Tower of Pisa.
What is the angle of the leanikng tower of Pisa at the present?
The current angle of the tower is about 3.97 degrees.
Why is the the Leaning Tower of Pisa not stable?
The tower is actually now fairly stable after many decades of restoration and engineering, but continues to lean at an angle. When the first three floors of the tower were built, it was found the tower was sinking into the ground on one side. Construction was halted for almost a century, which allowed the ground to settle and later support four more levels.
If a radio transmission tower is 190 feet tall how long should a guy wire be if it is to be attached 9 feet from the top and is to make an angle of 21 degrees with the ground?
A guy wire attached to a tower 181 feet from the base (190 - 9) and making an angle of 21 degrees with respect to the ground is 505 feet long. sin (21) = 181 / x x = 181 / sin (21) Note: An angle of 21 degrees with respect to the ground is unrealistic. It is probably more correct to say 21 degrees with respect to the tower, which is 69 degrees with respect to the ground. In this case, the guy wire is 194 feet long.
A guy wire from the top of the transmission tower at WJBC forms a 75 angle with the ground at a 55-foot distance from the base of the tower.How tall is the tower?
Well, darling, you've got yourself a right triangle situation here. Using some good ol' trigonometry, you can solve for the height of the tower. The tangent of 75 degrees is equal to the height of the tower divided by the distance from the base to the point where the guy wire touches the ground. So, the height of the tower is approximately 209 feet. Voilà!
A point is 200 feet from a tower The angle of elevation to the top is 18 degrees and the angle of elevation to the bottom is 15 degrees I think the tower is on a hill how tall is the tower?
Consider the following ._ . . . , ______ . , / . , / . , / . ______________/ Dotted line is to the top of the tower, and has an 18 degree angle with the ground Comma line is to the bottom of the tower, and has a 15 degree angle with the ground Visualize the two triangle that exist here: ._ . | . | . , | . , | . , | . , | . _________________| In both cases, the base of the triangle is 200 ft. The height of the dotted triangle is given as sin(18) * 200 = 61.80 The height of the comma triangle is given as sin(15) * 200 = 51.76 The top of the tower is represented by the dotted triangle, so it is 61.80ft above our observation point The bottom of the tower is represented by the comma triangle, so it is 51.76ft above our observation point. The height of the tower is the difference between these heights. 61.80 - 51.76 = 10.04ft The tower is a massive 10ft tall!
From the top of a fire tower the angle of depression is observed 25 degrees Find distance from the cabin to the foot of the tower if the tower is 149 m?
Suppose the distance is x.Then tan(25) = x/149 m so that x = 149*tan(25) metres = 69 metres, approx.
An amateur radio operator erects a 75 foot vertical tower for his antenna find the angle of elevation to the top of the tower at a point on level ground 50 feet from the base?
hehe erects
