Line AB contains points A(4, 5) and B(9, 7). What is the slope of AB? in/n win 0 Nin inn?

2/5

Step-by-step explanation:

you have to do slope formulation which is y2 minus y1 over x2 minus y1

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

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
