Step-by-step explanation:
sum of all the angles of a triangle=180°
let the 3 angles of the triangle be 3x,5xand 4x respectively,
A.T.P.,
=>3x +5x +4x =180°
=>12x=180°
=>x =180/12
=> x =15
* the angles of the triangle are =
3x=(3×15)°=45°
5x=(5×15)°=75°
4x=(4×15)°=60°
ANS) THE 3 ANGLES OF THE TRIANGLE ARE 45°,75°,60°.
