Solve for the angles x and y

I really really need help this is for a big test

Step-by-step explanation:

step-1: find the sum of the polygon interior angles

=(7-2)×180°

=5×180°

=900°

step-2: find x

according to the question

113+112+123+168+99+148+x=900

=>773+x=900

=>x=900-773

therefore

x=127

according to the question

127+y=180

=>y=180-127

therefore

y=53

answer: 20

step-by-step explanation:

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
