WebVideo transcript. Angle A is a circumscribed angle on circle O. So this is angle A right over here. Then when they say it's a circumscribed angle, that means that the two sides of the angle are tangent to the circle. So AC is tangent to the circle at point C. AB is tangent to the circle at point B. WebCalculate the area of a regular hexagon if the radius of the circle circumscribed is 6.8 cm. RT sides. Find the sides of a rectangular triangle if legs a + b = 17cm and the radius of the written circle ρ = 2cm. RT and circles. Solve the right triangle if the radius of the inscribed circle is r=9 and the radius of the circumscribed circle is R=23.
WebSep 5, 2024 · The diameter is C D = 2 R = B D 2 + B C 2 by the Pythagorean theorem, since ∠ C B D is inscribed in a semicircle, thus is a right angle. Now use the trigonometric properties to deduce that B H = B D sin α, and B H = B C cos α. We also have B H + B C = p, because this is half the perimeter of A B C.
