Question

Someone help me solve this problem

Answer 1

Same-side interior angles where a transversal crosses parallel lines are supplementary:

• 6y +4y = 180
• 90 +5x = 180

The solutions to these equations can probably be done in your head:

• y = 180/(6+4) = 18
• x = (180-90)/5 = 18

The angles at the bottom of the figure, shown as different, are actually the same: 90°.

The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.
