some problemsSector OAB is a quarter of a circle of radius 3. A circle is drawn inside this sector, tangent at three points as shown. What is the radius of the inscribed circle? Express your answer in simplest radical form. I see you have graph paper. You must be plotting something #3 20130810 23:14:15

Re: some problemshi bobbym, I've got methods for 2 and 3, but I'm waiting for some feedback on Q1 from the OP. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #8 20130814 04:54:18
Re: some problemsHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #10 20130814 10:58:43

Re: some problemsIn the triangle GYZ, YZ is the hypotenuse. and XY is, yes, the radius of the circle. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #12 20130815 10:43:07
Re: some problems10 + 5sqrt2. derp how did i not see that?!?!?! I see you have graph paper. You must be plotting something #13 20130815 17:29:38
Re: some problemsQ1 correct. Well done!
It can happen to us all. I nearly messed up an exam because I hadn't noticed that the length of a radius on one side of a circle was the same size as the radius on the other side of the same circle. doh!

Re: some problemsthanks, i got both of them. Triangle ABC has side lengths AB = 9, AC = 10, and BC = 17. Let X be the intersection of the angle bisector of \angle A with side \overline{BC}, and let Y be the foot of the perpendicular from X to side \overline{AC}. Compute the length of \overline{XY}. Equilateral triangle ABC and a circle with center O are constructed such that \overline{BC} is a chord of the circle and point A is the circumcenter of \triangle BCO in its interior. If the area of circle with center O is 48\pi, then what is the area of triangle ABC? In a triangle ABC, take point D on \overline{BC} such that DB = 14, DA = 13, DC = 4, and the circumcircles of triangles ADB and ADC have the same radius. Find the area of triangle ABC. Let denote the circular region bounded by x^2 + y^2 = 36. The lines x = 4 and y = 3 partition into four regions . Letdenote the area of region If then compute I see you have graph paper.
