The first ratio would be 3:4 (dividing by 5).
The second ratio would be 21:32 (also dividing by five).
To determine if they are equivalent rates, you must somehow make them even. Multiplying 3:4 by 7 would give you 21:28. Thus proving they are not equivalant.
You add up all the sides, so for example, the first 1, 5+4+5+4=18
Vertical angles are angles opposite of eachother and therefore the same. Since angle 2 is 93° that means angle 1 must also be 93°
