I don't understand any of the problems and how to solve them. I need explanation and solved.

Draw a picture, write a trig ratio equation, rewrite the equation so that it is calculator ready and then solve each problem. Round measures of segments to the nearest tenth and measures of angles to the nearest degree. 1. A 20-foot ladder leans against a 2. A 50-meter vertical tower is wall so that the base of the ladder is 8 feet from braced with a cable secured at the top of the the base of the building. What is the ladder's tower and tied 30 meters from the base. What angle of elevation? is the angle of depression from the top of the tower to the point on the ground where the cable is tied? 3. At a point on the ground 50 feet 4. From the top of a lighthouse 210 from the foot of a tree, the angle of elevation to feet high, the angle of depression of a boat is the top of the tree is 53. Find the height of the 270. Find the distance from the boat to the foot tree. of the lighthouse. The lighthouse was built at sea level. 5. Richard is flying a kite. The kite 6. An airplane rises vertically 1000 string has an angle of elevation of 570. If feet over a horizontal distance of 5280 feet. Richard is standing 100 feet from the point on What is the angle of elevation of the airplane's the ground directly below the kite, find the path? length of the kite string. 7. A person at one end of a 230-foot 8. The angle of elevation from a car bridge spots the river's edge directly below the to a tower is 320. The tower is 150 ft. tall. opposite end of the bridge and finds the angle How far is the car from the tower? of depression to be 570. How far below the bridge is the river? 230
