Answer:
by how much degrees should the heat be reduced in the last 5 minutes of banking
Cos A) 16/20 or 4/5
Tan A) 12/16 or 3/4
Sin A) 12/20 or 3/5
620*1.35=837 so 837ml is the answer
Set up and solve an equation:
3(90-x) = (180-x). Then 270 - 3x = 180 - x, or 270 - 180 = 2x.
90 = 2x, so x = 45 deg.
Is this true? 3(90-45) = (180-45)? If so, x = 45 degrees is correct.
For a polygon to be regular it must have all sides the same length and all interior angles the same.
