The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle? Sun Nov 15 2020 · answered. The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle? 40°. 70°. 100°. 140°. 2. See answers. report flag outlined. An isosceles triangle is a triangle with two equal sides. When two sides are equal two of its angles will be also equal. This are the base angles of the triangle. Let one of the base angle = x . Vertex angle is given a 40°. Angles in a triangle add up to 180°. ∴ 180 = 40 + x + x. 180 = 40 + 2x. 2x = 180 - 40. Answer by edjones (8007) ( Show Source ): You can put this solution on YOUR website! let the vertex angle=v and a base angle=b. v=2b-40 given. 2b+v=180 all the angles of a triangle add up to 180. profile. Brainly User. the 2 base angles are equal so the measure of 1 base angle = (180 - 42) / 2. = 69 degrees. 2x + 3 = 69. 2x = 66. x = 33. each base angle measure s 69 degrees. klondikegj and 246 more users … Mon Oct 19 2020 · The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is the value of x? What is the measur...
