WebIn a triangle, ABC, if m∠A = 60°, m∠B = 40°, then find the measure of angle ∠C. Solution: In ABC, ∠A = 60° and ∠B = 40° We know that the sum of angles in a triangle is 180°. ⇒ m∠A + ∠B + ∠C = 180° ⇒ 60° + 40° + ∠C = 180° ⇒ ∠C = 180° − ( 60° + 40°) ⇒ ∠C = 180° −100° ∴ ∠C = 80° One of the acute angles in a right-angled triangle is 400. Web4 Jan 2024 · One of the basic properties of triangles is that the sum of the measure of angles, in every triangle, is 180°.
