Question

help me? Picture below will medal

Answer 1

These are similar triangles...

Answer 2

the ratios of the sides will be the same.... to find out what x is then

\[\frac{ 84 }{ 7 } = \frac{ 156-x }{ x }\]

After you find x value,, Side AC = 156 - x

Answer 3

so it would be

\[84x = 1092 7x\]
\[91x= 1092\]

Answer 4

is that correct?

Answer 5

so x = 12? and AC = 156-12?

Answer 6

so @DanJS AC = 144

Answer 7

hi, back

Answer 8

84x = 7(156 - x)

84x = 1092 - 7x

91x = 1092

x = 12
