Answer:
a. AB = 3.4 ft
b. AE = 1.6 ft
Step-by-step explanation:
SOH CAH TOA reminds you of the relationship between trig functions and right triangle sides.
a. Cos = Adjacent/Hypotenuse
cos(28°) = BE/BA = 3 ft/BA
Multiplying by BA and dividing by cos(28°), you get ...
BA = (3 ft)/cos(28°) ≈ 3.4 ft
___
b. Tan = Opposite/Adjacent
tan(28°) = AE/BE = AE/(3 ft)
Multiplying by 3 ft, you get ...
AE = (3 ft)·tan(28°) ≈ 1.6 ft
Volume= 37. 7
V=π r² h/3 = π · 22 · 9/3 ≈37.69911
I hope this helps!
Answer:
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate.
so i assume it could be 162 sorry if i am wrong let me know if it is right or not
Since the interior is 170 the exteriro must be 10 degrees. There is a total of 360 degrees so 360/10=36 or 36 sides.
