∠c and ∠d are vertical angles with m∠c=−3x+58 and m∠d=x−2 . what is m∠d ?

m<D is

Step-by-step explanation:

Vertically opposite angles are said to be equal angles, thus;

                   m<C = m<D

So that,

              -3x + 58 = x -2

             -3x - x = -2 -58

               - 4x = - 60

                 x =

                 x = 15

Thus,

  m< D = x - 2

           = 15 - 2

           =

Therefore, m<D is
