Question

Please help I have quite a bit of points

a || b . Find the value of the star.
Record your answer as a decimal. Round to the nearest hundredth if necessary.

Answer 1

The star equals 96

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
