Please help as soon as possible 1. An overhead crane is suspended from a ceiling by two chains. One chain is 4.6 m long and forms an angle of 60° with the ceiling. The other chain is 6.4 m long. What angle does the larger chain make with the ceiling?

2. At noon, two tracking stations on Earth, 20 km apart, measure the angles of elevation of a rocket that was launched with a weather satellite. From Station A, the angle of elevation is 41° and from Station B it is 75°. Find the altitude of the rocket to the nearest tenth. Note: Both tracking stations are on the same side of the rocket.

3. A farmer has a field in the shape of a triangle. The farmer has asked the manufacturing class at your school to build a metal fence for his farm. From one vertex, it is 435 m to the second vertex and 656 m to the third vertex. The angle between the lines of sight to the second and third vertices is 49°. Calculate how much fencing he would need to enclose his entire field.

4. A balloonist at an altitude of 226 m observes the angles of depression of one point on the ground as 2 degrees, and another point as 3 degrees. The angle directly below the balloon and along the ground between the horizontal sight lines of the two points is 80 degrees. What is the distance between the two points?

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
