A_n=59-3(n-1), 1,2,3...
Find the first four terms of the sequence given by the following

9514 1404 393

  59, 56, 53, 50

Step-by-step explanation:

Use n = 1 through 4 and evaluate.

  a1 = 59 -3(0) = 59

  a2 = 59 -3(1) = 56

  a3 = 59 -3(2) = 53

  a4 = 59 -3(3) = 50

The first four terms are 59, 56, 53, 50.

i dont know

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
