    What will be inradius of a right angle triangle whose

    base is 12 cm & height is 35 cm ?
    A 3 cm Correct Answer Incorrect Answer
    B 4 cm Correct Answer Incorrect Answer
    C 10 cm Correct Answer Incorrect Answer
    D 5 cm Correct Answer Incorrect Answer

    Solution

    By pythogorus theorem, Hypotenuse 2  = Base 2 +Height 2 = 122 + 352 = 144 + 1225 = 1369, So Hypotenuse = 37; Now inradius of a right angle triangle = (Base + Height - Hypotenuse)/2 = (12 + 35 - 37)/2 = 10/2 = 5 cm
