Answer:
11/12
Step-by-step explanation:
6 7/12 - 5 2/3
=(6-5) + (7/12 - 2/3)
= 1 + 7/12 - 2*4 / 3*4
= 1 + 7/12 - 8/12
= 1 + 7-8 / 12
= 1 + -1/12
=11/12
Since we know that the two lines are parallel because of alternate interior angles (5x-20)=3x
then solve for x
5x-20=3x
-20=-2x
x=10°
looks like D...............
15 and 108
3*(30-25)=3*5=15
4*(12+15)=4*27=108
