Grace made tables of values to solve a system of equations. First, she found that the x-value of the solution was between 0 and 1, and then she found that it was between 0.5 and 1. Next, she made this table. Which ordered pair is the best approximation of the exact solution?
A. (0.9, 1.0)
B. (0.6, 0.7)
C. (0.7,0.2)
D. (0.5, 1.2)

answer: no

step-by-step explanation:

answer: rolling a number cube and flipping a coin.

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
