Consider the circle. geometry

  (a)  47°

Step-by-step explanation:

Inscribed angle ACE is half the measure of arc AE, so is 42°/2 = 21°. Angle ECD subtends the same arc as angle EBD, so has the same measure, 26°. Angle ACD is the sum of the angles that make it up:

  ∠ACD = ∠ACE +∠ECD

  ∠ACD = 21° +26° = 47°

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
