The height of the monument is 555 ft and the angle of elevation from the ground is 60°. If d is the distance from a man`s feet to the base of the monument than:
tan 60° = 555 / d
√3 = 555 / d
d = 555 · √3 = 555 · 1.732 = 320.44 ft.
The distance from the man`s feet to the top of the monument is:
320.44 ft · 2 = 640.88 88 ft.
Answer:
The distance from the man`s feet to the base of the monument is 320.44 ft ( just that is correct ).
Answer:
answer is 97.5
Step-by-step explanation:
a=80 +b=10+c=7.5 =180
97.5
If it's 5 percent salt, 5 percent = 0.05 and 0.05*200=10 (which is 5% of 200), therefore showing us that we need 10 ounces of salt. From a 40% solution (0.4), we need to figure out how many times 0.4 goes into 10, which is 10/0.4=25, showing us that we need 25 ounces of the salt solution. 200-25=175 ounces left for water
