I confused ,I'm not sure how to solve this

UST =40.4, RST=80.8

Step-by-step explanation:

Bisects means divides in two, therefore UST is the same as RSU (40.4) all you need to do to solve for RST is multiply 40.4 by 2 which is 80.8

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.
