Answer:
here's the solution,
let the given ratios as constants, by multiplying with same variable x
the angles will be 3x , 7x and 2x
now, we know the sum of the given angles measures 180°, since the sum of measures of all interior angles of a triangle is 180°
=》3x + 7x + 2x = 180°
=》12x = 180°
=》x = 15°
so, the measures of each angle is :
3x = 15 × 3 = 45°
7x = 15 × 7 = 105°
2x = 15 × 2 = 30°
and now, we can observe that the largest angle is 105°
