http://www.mathhomeworkanswers.org/235444/determine-equilibrium-wheels-weight-connected-inextensible
Two wheels each have a weight W and are connected to each other by an inextensible cord.. If they rest against smooth planes, one of which is inclined at an angle phi and the other is vertical. The center of the wheel on the vertical plane makes an an theta between the cord and the horzontal line of the center of the wheel. The cord is of length L.<br />
<br />
Determine the angle theta A.) interms of the parameters given and B.) with W = 10 lb., phi = 60 degrees.?<br />

In triangle ABC, PQ drawn parallel to BC meets the side AB at P and the side AC at Q. The lines CP and BQ intersect each other at S. SR drawn parallel to AB meets BC at R. Prove that BR RC = AQ AC<br />
<br />
Theorems: A line drawn parallel to a side of a triangle divides the other two sides proportionally. If two triangles are equiangular then the corresponding sides are proportional. If the three sides of a triangle are proportional to the three sides of another triangle, then the two triangles are equiangular.Geometry Answershttp://www.mathhomeworkanswers.org/225949/solve-the-question-based-on-the-theoremsWed, 07 Sep 2016 15:23:44 +0000What is the exact value of tan eleven and five degree
