Law of tangents formula
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 … WebAccording to the law of sines: Where a, b, c are the sides of the triangle, α, β, γ are the opposite angles, and R is the radius of the circumscribed circle. Let’s write down: It follows herein: and and Add a and b: Divide both parts by c: We use the Sum to Product Formulas of sines: We use the sine of a double angle formula: We get:
