I need help with this Question Dilate the original triangle. Use a dilation factor of 3. Use the point (4, 0) as the dilation center.
The Coords of my triangle are
A Coords are X3, Y1
B Coords are X6, Y5
C Coords are X8, Y2.

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

the answer is b.

surface area: 169π

volume: 366π
