Question

The angles of a triangle are( 3x-5 )° (5x-10)° and (9x-9)° find the degree measure.​

Answer 1

Answer:

Step-by-step explanation:

sum of the angles of a triangle  = 180°

3 x - 5 + 5 x - 10 + 9 x - 9    = 180

      17 x  -  24  = 180

              17 x  = 180  + 24

                   x  = 204/ 17

                       =  12

angles are  3(12) -5   ,  5(12) - 10 ,   9(12) - 9

               =   31° , 50°, 99°
