I have been told by several people that the following problem "NEEDS" to be solved using Trigonometry. I feel I am close to a solution in some other way, well here it is....

Slap a circle on a graph with a radius (A) centered on the origin

eqtn: x^2 + y^2 = A^2

Given that there is a specified number of degrees in a section of the circle, I want to find the length of the line underneath that ark.....

I start by passing a line with an arbitrary slope through the origin

then i pass a line perpendicular to the previous line

this gives a 90 degree angle

right there I could solve the system and find two intersections with the circle and they would be 90 degrees apart.

then use the distance formula to determine the length of the line under that particular ark...

My question: How could i find a solution given a number of degrees that isnt so easily determined

is there a way to find, using the slopes of the lines the number of degrees in that angle.

sorry for any confusion. I know it must be tough to decipher what im attempting to say since i don't know any terminology to simplify this problem
