Answer:
- Step1. Slope is zero
- Step2. Angles 5, 8, 9 and 12
Step-by-step explanation:
<u>Step 1</u>
Parallel lines have the same slope.
Gray Dr is parallel to Brodie Ln
They both are parallel to x-axis, therefore both have a zero slope.
<u>Step 2</u>
m∠6 = x°
Angles 5 and 8 are supplementary with angle 6, so they have a measure of (180 - x)°.
Also, since Gray Dr is parallel to Brodie Ln and Canon Rd is transversal, the angles 9 and 12 have the same measure. Because ∠6 and ∠10 are corresponding angles.
