6. A right triangle has one vertex on the graph of y = 9 - x?, x > 0, at (x, y), another at the origin, and the
third on the positive x-axis at (x,0). Express the area A of
the triangle as a function of x.

(-1,-0.5)

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

they charge the same amount at 20 minutes.
