Me. Brust and Mr. Kelly go hot air ballooning one day. Well... Mr. Kelly gets to go air ballooning while Mr. Brust has to drive around and follow the hot air balloon to pick Mr. Kelly when he lands. Just being themselves they decide to do a little math before they land. Mr. Kelly radios and tells Mr. Brust that the altimeter says that he is 100 feet off the ground. He then throws down a rope that is exactly 200 feet long and Mr. Brust attaches to his car so they can do some calculations. Mr. Kelly then radios down that he calculated the angle of depression to be 30°. Who is right? Why?

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
