In a triangle, Sum of all three angles is equal to 180°.
Therefore A + B + C = 180°     ------------------(1)
and given that, 2A = 3B = 6C
           ⇒      A = 3C, B = 2C
From eqn (1),
                     A + B +C = 180°
                ⇒ 3C + 2C +C = 180°
                ⇒ 6C = 180°
                ⇒ C = 180/6 = 30°
Therefore A= 3C = 3×30 = 90° and B = 2C = 2×30 = 60°

We know that the sum of 3 sides in a triangle are 180 degree.
Let
2A=3B=6C= k (say)
Therefore , k=180 ,
6C=180 ⇒C=180/6=30 degree
3B=180 ⇒B=180/3=60 degree
2A=180 ⇒A=180/2=90 degree.
Ans:The value of A is 90 degree.
