Answer:
120 pounds
Step-by-step explanation:
Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(120) = 144(100)
120x = 14400
x= 120 pounds
Since it is a regular hexagon, all 6 sides are the same length. That means that the 6 vertices divide the circle into 6 equal arcs. 360/6 = 60° for each arc. The arch between A and F is an intercepted arc for ∠FDA, and we know that inscribed angles are 1/2 of the measure of the intercepted arc. Since the arc measures 60°, that means that the angle would be 30°.
