Question

What is the length of line MN?
(Picture attached)

Answer 1

because the triangles are congruent you can set up a ratio

Answer 2

How? I'm terrible at ratios.

Answer 3

\[\frac{ MN }{ SN }=\frac{ RT }{ ST }\]

Answer 4

64.4?

Answer 5

Because the triangles are "similar" (they are not congruent because they are not the same, sry wrong term) the ratio between their sides should be equal.

Answer 6

Idk I haven't done it

Answer 7

28*23/33 whatever that is should be the answer

Answer 8

But that would be 19.515151515151

Answer 9

Then thats the answer

Answer 10

look at the picture and think for one second. Is it possible for that line to be longer than the base of the larger triangle??

Answer 11

\[\frac{ x }{ 23 }=\frac{ 28 }{ 33 }\]\[x=\frac{ 28 \times 23 }{ 33 }\]

Answer 12

mn/28=23/(23+10) solve for mn

Answer 13

i got 19.515151 which is reasonable :D

Answer 14

Hm, I'm used to full numbers, I guess my teacher tried to through in a decimal at us this time. Thanks(:
