Math ? ? will reward brainliest! what is m∠svt?

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

the answer is 79

Step-by-step explanation:

180-79=101 87-33 -*2

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
