a Wire i strecked from the ground to the Top of an antenna tower. The wire...
An antenna tower has two wires stretching from the top to the ground to support it. For each wire the angles of elevation are as follows: Ware 1 Wire 2 Angle of elevation 689 43° Wire 1 is separated from Wire 2. by x m. along the ground. If the height (h) of the tower is 15m, find the distance x in metres. k xm *
please answer both! i will upvote 7) A radio tower 500 feet tall, and the ground on one side of the tower has an inclination to the horizontal of 10 degrees while the other does not. How long should the wires be if wire sis to be connect to the top of the tower and wiret is to be connected to the middle of the tower. Both wires are secured at 1000 feet directly above and below the base of...
The angle of elevation to the top of a tower from point A on the ground is 19.5 degrees .19.5°. From a point B,38.5 feet closer to the tower, the angle of elevation is 21.7°. What is the height of the tower in feet?
14. A wire holding a tower makes a 73° angle with level ground. At a point 30 feet farther from the tower than the base of wire (but on the same side as the base of the wire), the angle of elevation to the top of the tower is 35º, (see Figure (2) in the attachment Final Exam Figures.pdf). (a) Determine the unknown agles of triangle ABC. (b) Use the law of sines (apply it to triangle ABC) to calculate...
600 Tool wire stretches from the top a tower to a point on the ground. If the angle it makes with the level ground is exactly 1 radian, then how tall is the tower? 14. A surveyor, standing at point P, measures that it is 2.82 miles to a point on one side of a nearby lake. She also measures that it is 3.56 miles to a point R on the other side of the lake. If the angle between...
The FM radio station KAMB broadcasts from an antenna atop a 170 meter tall radio tower at a frequency of 90 MHz with a total radiated power of 40 kilowatts. Neighbors have complained about problems they attribute to excessive radiation from the tower, but the city engineer who measured the radiation level near the base of the tower found it to be well below the accepted standard. You have been hired by the HOA to assess the engineer's report. You...
A stone thrown horizontally from the top of a 24-m tower hits the ground at a point 18 m from the base of the tower. (Ignore any effects due to air resistance.) (a) Find the speed at which the stone was thrown. (b) Find the speed of the stone just before it hits the ground.
A stone thrown horizontally from the top of a 22-m tower hits the ground at a point 20 m from the base of the tower. (Ignore any effects due to air resistance.) (a) Find the speed at which the stone was thrown m/s (b) Find the speed of the stone just before it hits the ground m/s eBook
At a point on the ground 2424 ft from the base of a tree, the distance to the top of the tree is 44 ft more than 33 times the height of the tree. Find the height of the tree. The height of the tree is ft.
A communication tower (the side CB) is located at the top (the point C) of a steep hill. The angle of inclination of the hill is 58 degrees. A guy wire is to be attached to the top (the point B) of the tower and to the ground (the point A), 95 m downhill from the base of the tower (the side AC). The angle ∠BAC is 12 degrees. Find the length of cable (the side AB) required for the...
