Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees

Answer:

The price increased by %60. Why? Because 160% of 500 is 800, so that must mean the percent only increased by 60.
The Formula for the volume of a sphere is 
- r --> length of radius --> 2ft
