Ayo can anyone help with this

Answer

Step-by-step explanation:

because tan(45) =1 . then a /6 =1 . then a =6 also sin(45) = /2 .so a/b = /2

.so 6/b = /2.so a = 6

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.
