Which expression is equivalent to ; 2332
O 1
0-1
o i
O -i

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
