You can rearrange this to find one of the legs using the other two sides of the right triangle:[tex]x=\sqrt{24^2-10^2}=\sqrt{576-100}=\sqrt{476}=\sqrt{2^2... | 677.169 | 1 |
Hence, it appears that evidently its role is to reveal the substitution rules that are utilized all through the remainder of Book II, rather than to current a particular geometrical statement. In the propositions that observe, squares are also identified by the phrase square on a straight-line, where the specific ident... | 677.169 | 1 |

In AB take any point D; from A, with the radius AD, describe an arc intersecting AC in E; join DE, bisect it in F (8. 1.), and join AF: the angle DAF is equal to the angle EAF.
Because the triangles DAF and EAF have the side DA equal to EA (Def. 54. 1.), DF equal to EF, by the construction, and FA common; the three si... | 677.169 | 1 |

I got it but I forgot the exact answer, but it's a really simple problem anyways it just involved many right triangles so you can just do a^2 + b^2= c^2 to get the answer, if you still need it I can redo the problem for you and get the answer | 677.169 | 1 |
