What is 4x-6=122 +6 +6 4x=128 x=32

400

What are Vertical Angles.
400

Skew

400

What is the relationship between angles 1 and 4? (angles opposite each other across two intersecting lines)

400

What is <7=150; and 3x=150 x=50

500
When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.
What are Alternate Interior Angles.
500
Coplanar lines that do not intersect.
What are parallel lines.
500

If the measure of angle 1 is 37, what is the measure of angle 8? (Alternate exterior of 2PLCbT)

What is 37

500

If m<1=98°, then find the measure of <2 (same side interior) and <3 (alternate interior of 2PLCbT)

What is 82 and 98 respectively

500

If the measure of <4 is 8x+35 and the measure of <6 is 2x+5, then find the value of x and find the measure of <8? (<4 and <6 are same side interior angles of 2PLCbT)

What is 8x+35+2x+5=180 10x+40=180 10x=140 x=14 Now plug into <4 because it is congruent (corresponding) to <8. 8(14)+35=112 so <8=112.
