WebOC is perpendicular to AC (line tangent to a circle is perpendicular to the radius drawn to the point of tangency), making OAC a right triangle. OA is the hypotenuse, OC and AC are the legs. So you can set the equations for the Pythagorean Theorem: 1) 4^2+x^2= (2+x)^2. … WebA tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The angles in a triangle add up to 180, so ∠BCA + ∠OAC + y = 180 …

WebA tangent is a line that just skims the surface of a circle. It hits the circle at one point only. There are two main theorems that deal with tangents. The first one is as follows: A tangent line of a circle will always be perpendicular to the radius of that circle. It will always form a right angle (90°) with the radius.
