Answer:
= 250
Step-by-step explanation:
To obtain any term in the geometric sequence multiply the previous term by the common ratio r
here r = - 5 and = - 2, hence
= - 2 × - 5 = 10
= 10 × - 5 = - 50
= - 50 × - 5 = 250
distance = 500 feet
Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is
=
=
completing the required values gives
=
( cross- multiply )
60l = 30 × 100 = 3000 ( divide both sides by 60 )
l = 500
distance across the swamp is 500 feet
