WebApr 24, 2014 · Circle Inscribed - Triangle Problems. The base of an isosceles triangle is 16 in. and the altitude is 15 in. Find the radius of the inscribed circle. The intersection of the angle bisectors of an isosceles … WebSolution: We know that the sum of the angles of a triangle adds up to 180°. Therefore, the unknown angle can be calculated using the formula. Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3. ⇒ 180° = 45° + 63° + Angle 3. ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72°. ∴ The third angle is 72°. maker\u0027s mark red white and blue wax
