Answer:

The star equals 96

Step-by-step explanation:

The star will be equal to 5x-14 because they are vertically opposite.

The two exterior angles are supplementary.  Set up the equation

5x - 14 + 3x + 18 = 180        Combine the terms on the left.

8x + 4 = 180                        Subtract 4 from both sides

8x = 180 - 4                         Combine

8x = 176                               Divide by 8

x = 176 / 8

x = 22

===================

5x - 14

5*22 - 14

96
