If the angles of a triangle are in the ratio 1:2:3, what will be the value of angles in degrees?
If the angles of a triangle are x∘, 2x∘ and 3x∘, then the value of x is __ (in degrees).
(a) What is the value of x in the figure given below if it is known that perimeter of the triangle is 86?
(b) Frame an equation for the following case and find the value of the unknown: In an isosceles triangle, the vertex angle is twice of either base angles. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees). [3 MARKS]
