Plz will give brainliest answer and 20 !

on a piece of paper, use a protractor and a ruler to construct △abc with ab=6 cm , m∠a=80° , and m∠b=50° .

what is ac ?

3 cm

6 cm

9 cm

12 cm

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
