7 and 2 cannot be the lengths as on a triangle they're two equal side so two 3s or two 5s
Since Sarah’s age is 2x of Bob’s age (which is 42) Sarah is 84.
1) From the data, we can see that

is given.
2) Next,

since they are alternate angles.
3) By substitution, these means that

4) Finally, a || b since

this is because, angle 7 and angle 8 are corresponding angles.
Corresponding angles are angles that are on the same corner at each intersection. For instance, 2 and 6
4 and 8, 1 and 5, 3 and 7
In our case, 7 and 8 are corresponding angles
