Respuesta :

These two angles are vertical angles and they are equal to each other so

5y+ 9 = 8y -33 now solve for y

-5y       -5y  

      9  =  3y  -33

    +33         +33

    42  = 3y

    /3       /3

   14   =   y

now SVT  is 5y + 9  and we know y

5(14) + 9  = 70 + 9 = 79

Answer:

the answer is 79

Step-by-step explanation:

180-79=101 87-33 -*2
