A boy is flying a kite. His kite string is extended 50 meters long. The boy is 1.7 meters tall, and the angle of elevation of the kite to the boy's hands is 12°. How high is the kite flying above the ground?
Answer:
12.1 meters
Explanation:
Please check the attached image for a diagram of the question
We are given the value of the hypotenuse and we are to determine the value of the opposite side. Thus, we would use sin
Sin = opposite / hypotenuse
sin 12 = opposite / 50
0.2079 = opposite / 50
opposite = 0.2079 x 50 = 10.4 meters
height of the kite above the ground = 10.4 + 1.7 = 12.1 meters

Describe how the rotation of Earth around its own axis and its revolution around the sun affect sunrise and sunset. Explain why will this be different from outer space.
Answer:
since earth rotates on a tilted axis we experience night and day, and also different seasons. while being tilted on our axis we can experience longer days and shorter night when pointing towards the sun (summer), and shorter days and longer night pointing away from the sun (winter). you would experience a difference in space because you wouldn't be rotating on a axis any more. you would experience the same night and day patterns every day.
