If the angles of a triangle are in the ratio 2:3:5, then the measure of the least angle of the triangle is
Given, Â angles of the triangle are in the ratio 2:3:5
Let the angles of the triangle are 2p, 3p, 5p respectively
$$=$$>Â 2p + 3p + 5p =Â $$180^{\circ\ }$$
$$=$$>Â 10p = $$180^{\circ\ }$$
$$=$$> Â p =Â $$18^{\circ\ }$$
$$\therefore\ $$Least angle of the triangle = 2p =Â $$2\left(18^{\circ\ }\right)$$ =Â $$36^{\circ\ }$$
Hence, the correct answer is Option B
