Question

if the angles of a triangle are in the ratio 3:4:5 then which is the largest angle​

Answer 1

Step-by-step explanation:

Let the angles are 3x°, 4x° and 5x°

Sum of angles of triangle =180 °

3x° + 4x° + 5x° = 180 °

12x° = 180 °

X° = 180/12

x = 15 °

Largest angle =5x °

= 5 ×15°

= 75° ANS.
