Simplify the expression:
(10 + 2) + (4 + 4) =
O a 36
сь 6
oc 9

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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

hope this !
