500
If the measure of anlge 1 is 37o, what is the measure of angle 8? What is the angle relationship
What is 37, Alternate Exterior
500

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?
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=147.
