Answer 1

We Know sum of all angles of a Δ is 180°

Now,

3x + ( 4x + 5) ° + ( 5x -17 )° = 180 °

=> 12x -12° = 180°

=> 12x = 192°

=> x = 192 /12

=> x = 16 °

Hence, required value of x is 16°

Answer 2

we know that the sum of angle of triangle is 180

then,

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

12x-12=180

12x=180+12

12x=182

x=182/12

x=16 answer.
