14. a. A man observes the angle of elevation of the top of a vertical tower to measure 25°. He walks a distance
of 250 feet toward the tower and in line with the foot of the tower and then observes the angle of
elevation of the top of the tower to measure 50°. Find, to the nearest tenth of a foot, the height of the
tower.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
