Which is a counterexample to the conjecture? the product of any two consecutive integers is a composite number.
a. 3 • 4 = 12
b. 30 • 31 = 930
c. 1 • 2 = 2
d. 10 • 11 = 110

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
