BRAINLIEST!!
Please at least take a look

The answer to your question is below

Step-by-step explanation:

1) The triangles are similar by the AA postulate so use proportions to find x.

          x/207 = 170/90

solve for x

          x = 207(170/90)

          x = 207(1.89)

         x = 391 ft

2) These triangles are similar so use proportions to solve it

          x/138 = (x + 60)/207

         207x = 138(x + 60)

         207x = 138x + 8280

          207x - 138x = 8280

                      69x = 8280

                         x = 8280/69

                         x = 120

1) 391 ft

2) 120

Step-by-step explanation:

Using similar figures

X/170 = 207/90

X = 170 × 207/90

X = 391 ft

X/(X+60) = 138/207

207X = 138X + 8280

69X = 8280

X = 120

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.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
