(b) 17% was above her score.
Step-by-step explanation:

b) Percentage of score which were above her score?
Solution:
First of all, let us learn about the term "Percentile"
Percentile is the value below which the certain percent of people/marks fall.
Therefore, when we say percentile of someone's score is [tex]x[/tex], then there are [tex]x\%[/tex] of scores are at the same level or below.
And [tex](100-x)\%[/tex] of the scores are above this level.
Therefore, we can say that:
83% of the scores were at the same level or below the score of Angela.
And [tex](100-83)\% = 17\%[/tex] of the scores were above the score of Angela.
