Say x is how old Ben is now. Ben’s age 16 years from now is the same as 3 times his current age, so:

x + 16 = 3x
2x = 16
x = 8

Ben is 8 years old.

First, do 16 x 3 to get 48. Then subtract 16 and youll get 32

we know that
in the triangle ABC
∠A+∠B+∠C=180°
∠C=180-(86+69)-----> ∠C=25°
Applying the law of sines
b/sin B=c/sin C------> b=c*sin B/sin C-----> b=82*sin 69/sin 25
b=181.14 ft

the answer is
181.14 ft
