I would have had the answer a whole lot sooner if I would have read the question properly. The figure in the circle is called a cyclic quadrilateral. It has the odd property that the angles that are opposite each other add up to 180o.

So DEB + DCB = 180o

DEB = 180 - 87

DEB = 93o

Note: The arcs marked 60 and 76 have nothing whatever to do with this problem.

Convert the rate 1000 ounces per 2 hours to cups per minutes?

Andrews [41]

125 cups in 120 minutes (because 1000 oz/8 = 125 cups and 2 hrs is 120 minutes)

$\frac{125}{120} = \frac{n}{1}$

now reduce the fraction by dividing the numerator and denominator by 5 = (optional)
$\frac{25}{24} = \frac{n}{1}$
So 24n = 25 Divide both sides by 24
n= 1 1/24 cups per minute
