Question

The angles of a triangle are In ratio 1:2:3determine the three angles

Answer 1

Ratio of triangles is 1:2:3   their sum is 180.    So x + 2x. +3 x. 6x =180 x = 30.   X 30.   2x.  60.   3x.  90

Answer 2

the angle of triangle will be 1x, 2x and 3x
we know that sum of a triangle is 180 degree
so,


$1x + 2x + 3x = 180 \\ 6x = 180 \\ x = \frac{180}{6} \\ x = 30 \\ \\ \\ hence \: agnles \: are \: 1 \times 30 = 30 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2 \times 30 = 60 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3 \times 30 = 90$
