    Question

    The angles of a triangle are in parallel series, the

    ratio of the degrees of the minimum angle and the radians of the maximum angle is 60 :π , then how many degrees are those angles?
    A 30°,60°,90° Correct Answer Incorrect Answer
    B 35°,65°,90° Correct Answer Incorrect Answer
    C 40°,50°,90° Correct Answer Incorrect Answer
    D 40°,55°,85° Correct Answer Incorrect Answer

    Solution

    Given: (minimum angle)/(maximum angle ) = 60/π =   60/180  =  1/3 ∴ The minimum angle is x then maximum angle will be 3x… Let the three angle of the triangle is a, b, c in parallel series….then  Middle angle b = (a+c)/2 b = (x+3x)/2 = 2x  the sum of three angles of a triangle = 180° => x + 2x +3x = 180° => 6x =180°  => x = 30°  Then – Angle of triangle = 30° ,60°  ,90°
