m∠G = m∠H = 50

m∠I = 80

Step-by-step explanation:

m∠H = m∠G              {Isosceles triangle property}

5x - 5 = 3x + 17               {Subtract 3x from both sides}

5x - 3x - 5 = 17               {Combine like terms}

    2x - 5  =  17                 {Add 5 to both sides}

         2x  = 17 + 5

         2x = 22

           x = 22/2

x = 11

m∠H = 5x - 5

        = 5*11 - 5

         = 55 - 5

m∠H = 50

m∠G = m∠H = 50

m∠G + m∠H + m∠I = 180   {Angle sum property}

50 + 50 + m∠I = 180

     100 + m∠I   = 180

               m∠I  = 180 - 100

              m∠I = 80
