7g5

• Find an unknown angle when you know the other angle in a straight line (they add to 180°).
• Use vertical angles and adjacent angles in intersecting lines to figure out missing measures.

7g5

• Find the value of a missing variable by keeping both sides of an equation balanced.
• Use addition and subtraction to undo numbers around a variable and isolate it.
• Solve for an unknown angle measure when the equation includes a variable.
