Answer:
The answer is 17%
explanation:
One way to find percents is to multiply the number you're trying to find the percent of (120) by whatever percent you're looking for (0.17, 0.2, 0.8, etc) If you multiply 120*0.17, you'll get about 20, which is how much was the amount of degrees lost.
30% converted to a decimal is 0.30
310 x 0.3 = 93 students play an instrument
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters
Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters
Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
The answer is 45. Because if you do 15 times 3 it would give you 45. So answer is 45cm
