Math Problem Statement

Solve for x: Given the angles (8x - 31)° and (5x + 17)° as corresponding angles formed by a transversal and parallel lines.

Solution

The image shows a diagram with two parallel lines (presumably PVPV and QTQT) intersected by a transversal line VWVW. The problem asks to solve for xx given the angles:

  • Angle PVW=(8x31)\angle PVW = (8x - 31)^\circ
  • Angle WQT=(5x+17)\angle WQT = (5x + 17)^\circ

These angles are corresponding angles, meaning they are congruent because PVQTPV \parallel QT and VWVW is a transversal.

Therefore, we can set up the following equation:

8x31=5x+178x - 31 = 5x + 17

Solving for xx:

  1. Subtract 5x5x from both sides: 8x5x31=178x - 5x - 31 = 17 3x31=173x - 31 = 17
  2. Add 31 to both sides: 3x=483x = 48
  3. Divide by 3: x=16x = 16

Thus, x=16x = 16.

Would you like further details on this? Here are 5 related questions to consider:

  1. How do corresponding angles relate when a transversal intersects two parallel lines?
  2. Can you explain why corresponding angles are congruent?
  3. What are alternate interior angles, and how do they differ from corresponding angles?
  4. How would the solution change if the angles were supplementary instead of congruent?
  5. How can you check if two lines are parallel based on the angle relationships?

Tip: When dealing with parallel lines and a transversal, remember that corresponding, alternate interior, and consecutive interior angles can help determine angle relationships.
