B. represents a dialation
You just need to know that all sides need to have the same measurement because it is a equilateral triangle.
Answer:
See Below
Step-by-step explanation:
Ok, so in this problem you have some vertical angles. These are angles oppisites from each other. Therefore; d = 52, f = ?, and e = 77. All the angles added together will = 360. Let's add up the angles we know and subtract the whole from 360.
52 + 52 + 77 + 77 = ?
104 + 154 = 258
360 - 258 = 102
Since we know that f and the unlabeled angle are the same, we need to divide this total between the two of them.
102/2 = 51
Therefore;
d = 52
e = 77
f = 51
Boys 4/9 = 44.44% Girls 5/9 = 55.55%
Fraction to percentage: Divide the top by the bottom then multiply the result by 100
