Answer:
B= A = 68
Step-by-step explanation:
ACE = BCD similar triangles. Similar triangles have equal angles.
A=B
C=C
D=E
This means if we can find angle B, we know angle A
BCD is a triangle so it equals 180 degrees
B+C+D = 180
B + 74+38 = 180
Combine like terms
B +112 = 180
Subtract 112 from each side
B +112-112 = 180-112
B = 68
Since we know angle B, we know angle A
B= A = 68

14/5 = 2.8
Answer:
7/10
Step-by-step explanation:
red + green = 50 + 20 = 70 marbles
Total marbles = 50 + 30 + 20 = 100 marbles
P(red or green) = 70/100
P(red or green) = 7/10
