3) Triangle ABC, angle A = 70, angle C =62, and BC = 7.3. To the nearest
tenth, what is AB?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

make sure you have version 2.50

try looking in the very back of the book : )
