Angle-A and angle-B are alternate interior angles with parallel lines cut by a transversal. That tells you that the two angles are EQUAL. So you can write
8x + 78 = 2x + 114 ,
and it should all be smooth sailing for you from that point.
First, make the fractions both have common denominators, so 3/8= 9/24 and 5/12= 10/24. Then add them up and you get 19/24
Answer:
D. 12%
Step-by-step explanation:
3/25=x/100
300=25x
x= 12%
