Answer:

17) Congruent because two sides are congruent and so is the 90 degree vertical angle.

18) Congruent because they have a congruent leg and congruent angle, and they share a side which is congruent to itself. (SAS)

19) Congruent because all three sides are congruent (SSS)

20) congruent, all three sides are the same (SSS)

Sydney planted 5/9 of her fall flowers. she had 63 unplanted flowers to start how many flowers does she have left to plant

Gwar [14]

Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.
