Step-by-step explanation:

<h3>Part A</h3>

<u>Angle measures:</u>

  • a = x = z = 51° (as vertical angles and corresponding angles)
  • b = d = y = w = 180° - 51° = 129° (as supplementary angles and corresponding angles)
<h3>Part B</h3>

Supplementary angles for a linear pair and sum to 180°.

<u>Examples are:</u>

  • a and b or
  • a and d or
  • x and y etc.

Solution:

Given:

  • An angle which measures 51°

<u>Using the given measure of an angle, we can identify all the angles.</u>

  • a° = 51° (Vertically opposite angles)
  • b° = 180 - 51 = 129° (180° angle)
  • d° = b° = 129° (180° angle)
  • w° = 129 (Alternate inner angles)
  • x = a = 51° (Alternate inner angles)
  • z = x = 51° (Vertically opposite angles)
  • w = y = 129° 9 (vertically opposite angles)

<u>We can tell that:</u>

  • a = x = z = 51°
  • b = d = w = y = 129°

Supplementary angles are pairs of angles that sums up to 180°.

<u>Example of supplementary angle:</u>

  • ∠a and ∠b are supplementary angles because they sum up to 180°.

The graph below shows a system of equations:
Nostrana [21]
3y = -2x + 2
y = x + 4 (Substitute the y)

3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x       +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2         - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10 
This is your x-coordinate
