To find the distance across a river, a surveyor chooses points A and B, which are x = 450 ft apart on one side of the river (see the figure). She then chooses a reference point on the opposite side of the river and finds that LBAC 82° and LABC
52º. Approximate the distance from A to C. (Round your answer to the nearest foot.)

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

r = 78539458390583095803458309458039485093485 or just 3
