theta is 78 degrees, alpha is 85 degrees

Step-by-step explanation:

use the parallel lines

alternate interior angles means that theta + 112 = 180

and since the alternate interior of the 85 degree angle is a vrtical angle of alpha, they are equal

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.
