The angles of a triangle are x 5 deg 2x ndash 3 deg and 3x 4 deg The value of x is ........

Quantitative Aptitude ( CCS) Trignometry

The angles of a triangle are (x + 5)°, (2x – 3)° and (3x + 4)°. The value of x is

Sum of angles of a triangle = 180°
∴ x + 5 + 2x – 3 + 3x + 4 = 180°
⇒ 6x + 6 = 180°
⇒ 6x = 174°
⇒ x = 29
