B'C'=(36^2+15^2)^1/2
B'C'=39
From similar Triangles
AB/A'B' =13/39
AB=5 |

Here.
C'B'=39.
But CB=13.
So CB=1/3 part of C'B'.
Then AB=1/3 part of A'B' (triangles are similar).
So AB=5. |

(36^2+15^2)^1/2=39
According to A'B'C'
tanx=36/15
x=67.38
is equals to <B
cos67.38=AB/BC=AB/13
So, AB=5 |

B'C'=(36^2+15^2)^1/2
B'C'=39
From similar Triangles
BC/B'C' =13/39 =0.33333
AB=A'B' x 0.333 = 5. |
