TRIGONOMETRY:1. Three poles on a level ground. Their bases form an equilateral triangle with sides 8m long. If the heights of thepoles are 4,6 and 10 meters, find the three dimensions of the triangle formed by their tops.2. If tan 0= x2, which of the following is correct? Defend your answer.a. cos e = 1/v(1+x^4)b. sin e = 1/v(1+x^4)c. csc e = 1/v(1+x^4)d. cot e = 1/(1+x^4)3. In a triangle ABC, find the side c if angle C=100, side b=20 and side a=15.4. A man standing 9m above the ground observes the angles of elevation and depression of the top and bottom of amonument as 20°20' and 40°40', respectively. Find the height of the monument.5.

An exit ramp from one freeway to another freeway forms a 900 arc of a circle. The ramp is scheduled for resurfacing. As shown, its inside radius is 370 ft, and its outside radius is 380 ft. What is the area of the ramp to the nearest integer?
When the Radius Increases a. A rope is wrapped tightly around a wheel with radius of 2 feet. If the radius of the wheel is increased by 1 foot to a radius 3 feet, by how much must the rope be lengthened to fit around the wheel? b. Consider a rope wrapped around the Earths equator. We noted in Exercise 17 that the radius of the Earth is about 4000 miles. That is 21,120,000 feet. Suppose now that rope is to be suspended exactly 1 foot above the equator. By how much must the rope be lengthened to accomplish this? The Size of the Earth The radius of the Earth is approximately 4000 miles. a. How far is it around the equator? Hint: You are looking for the circumference of a circle b. What is the volume of the Earth? Hint: The volume of a sphere of radius r is given by 43r3. b. What is the surface area of the Earth? Hint: The surface area of a sphere of radius r is given by 4r2.
