A museum was designed without windows, but a truncated cylindrical skylight lightens the building. In the development of this, the architect has areas where the angles formed at junctures are vertical angles.
If a pair of vertical angles measures 5x - 54 and 3x -24, find the measures of the angles.
since vertical angles are equal,
5x-54 = 3x-24
2x = 30
x = 15
The angles are 21 degrees
