Question

If the masures of the angles of ∆ABC are in the ratio 1: 2:3, then the measure of the smallest angle is
(1) 30 (i) 60 (1) 90 (iv) 1 20"​

Answer 1

Answer:

30 degree...............

Answer 2

Answer :

30°

Step-by-step explanation:

GIVEN RATIO : 1:2:3

sum of the angles of triangle =180°

A +B +C =180°

1k + 2k + 3k =180°

6k= 180°

k =180÷6

k=30°

Therefore the measure of the smallest angle = 30°
