Question

Three angles of a triangle are in the ration of 3.4.5 Find the measures of each of the three anghes What type of triangle is it ?​

Answer 1

ANS-

Let the angle be 3x,4x,5x

3x+4x+5x= 180

12x= 180

x= 180/12

x= 15

1st angle = 3x= 3×15=45°

2nd angle = 4x=4×15=60°

3rd angle = 5x= 5×15=75°

So it's an acute angle triangle
