Question

if the angles of a triangle are (3x),(4x+5) and (5x_17) thenfind the value of 'x' ​

Answer 1

according to the law the sum of all the angles is equal to 180

so 3x+4x+5+5x-17=180

12x-12=180

x = 16

Answer 2

Answer:sum of all angles of a triangle =180°

3x+4x+5+5x-17=180°

12x-12=180°

12x=180°+12°

12x=192°

x=192/12°

x=16°
