I like to use Math way it does a lot of math and calculator soup
C = 2×pi×r
72 = 2×pi×r
so r = 36/pi
DE = 30deg×36/pi
DE = (pi/6)×(36/pi) = 6cm
The answer in simplified form is {5x^2+1}{2x+1}

Answer: -5/4</h3>
=======================================================
Explanation:
The terminal point is at (x,y) = (3,-4)
Apply the pythagorean theorem to find that x^2+y^2 = r^2 solves to r = 5. This is the length of the hypotenuse.
Then we can determine the cosecant of the angle theta using the formula below
csc(theta) = hypotenuse/opposite
csc(theta) = r/y
csc(theta) = 5/(-4)
csc(theta) = -5/4
Side note: csc = 1/sin
Answer:
32% of 13 is 3.84
Step-by-step explanation:
but if your doing estimate one of those it would be 1/3*12
hope that helped
