I love u forever if u do my hw for me :(

this is 9 grade math.

Step-by-step explanation:

I failed 9 grade math.

Step-by-step explanation:

Isosceles Triangle property : The sides opposite to equal angles are equal.

1) m∠U = m∠S      {Isosceles Triangle property}

  m∠U = 54  

m∠U +  m∠S +m∠T= 180  {Angle sum property of triangle}

54 + 54 + m∠T = 180

      108 + m∠T = 180  

                m∠T= 180 - 108

               m∠T = 72

2)m∠M = m∠N  = x    {Isosceles Triangle property}

m∠M + m∠N + m∠L = 180     {Angle sum property of triangle}

x + x  + 28 = 180

2x  + 28      = 180

           2x = 180 - 28

           2x = 152

              x = 152/2

              x = 76

m∠M = 76

m∠N = 76

3) m∠E + m∠G + m∠F = 180

23 + 23 + m∠F = 180

        46 + m∠F = 180

               m∠F = 180 - 46

              m∠F = 134

EF = FG                   {Isosceles Triangle property}

EF = 18 in

4) Triangle PQR is an equilateral triangle

m∠P = m∠Q = m∠R = 60

6) 9x - 25 + 9x - 25 +  104 = 180      {Angle sum property of triangle}

                 18x - 50 + 104 = 180

                          18x + 54 = 180

                                18x    = 180 - 54

                                 18x = 126

                                    x = 126/18

x = 7

8) It is an equilateral triangle. So, all the angles are equal.

4x + 8 + 4x + 8 + 4x+ 8 = 180     {Angle sum property of triangle}

4x + 4x + 4x + 8 + 8 + 8 = 180

                         12x + 24 = 180

                                 12x = 180 - 24

                                 12x = 156

                                    x = 156/12

x = 13
