Please answer number 5 ASAP.thank you III Solve the ff. problems using trigonometric or inverse trigonometric functionsShow illustration, define variables used and give a detailed solutions.1. In the right triangle ABC, AB = 2, BC = 4 and ED is a line parallel to AB. Find theangle a = angle BAD which minimizes the distance L, where L = AD + ED2. At what point on the line y =b does the line segment from (0,0) to ( a,0) subtend thegreatest angle.3. Find the angle of the largest right circular cone which can be inscribed in a sphere ofradius 9 inches.4. A statue 10 feet high is standing on a base 13 feet high. If an observer's eye is 5 feetabove the ground, how far should he stand from the base in order that the anglebetween his lines of sight to the top and bottom of the statue is a maximum. (How farshould he stand to get the best view of the statue.5. A steel girder 27 feet long is to be moved on rollers along a passageway 8 feet inwidth and into a corridor at right angles to the passageway. If the horizontal width ofthe girder is neglected, how wide must the corridor be in order that the girder can goaround the corner?

A 20 meter line is used to tether a helium-filled balloon. The line makes an angle of approximately 85 with the ground because of a breeze. (a) Draw a right triangle that gives a visual representation of the problem. Label the known quantities of the triangle and use a variable to represent the height of the balloon. (b) Use a trigonometric function to write and solve an equation for the height of the balloon. (c) The breeze becomes stronger and the angle the line makes with the ground decreases. How does this affect the triangle you drew in part a? (d) Complete the table, which shows the heights (in meters) of the balloon for decreasing angle measures . (e) As approaches 0, how does this affect the height of the balloon? Draw a right triangle to explain your reasoning.
