In the diagram, m< 3 =120 and m< 12=80. which angle measures are correct? check all that apply.

Step-by-step explanation:

Given are parallel lines e and f

Also given that angle 3 =120 and angle 12 =80

Two transversals cut them

By axiom of parallel lines we have corresponding angles equal, alternate angles equal and interior angles are supplmentary

Using these we get

1= 180-120 =60

2=120: 4=60: 5=60: 6=120:7=120 and 8=60

Similarly for other transversal we get

10=100:13=80:10=100:14=100

Hence all are right except 6 and 10.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

just sum

10 + 10 = 20
