Answer:</h3>
<h3>
Step-by-step explanation:</h3>
If Alex cut his wire 18 times, he ended up with 19 equal pieces. He kept 7, so has 7/19 of his 1/3 of the wire.
Bob cut his wire 20 times, so ended up with 21 pieces, of which he kept 9. So he has 9/21 = 3/7 of his 1/3 of the wire.
Claudia kept 1/13 of her 1/3 of the wire, so has the smallest piece.
Bob kept (3/7)·(1/3)·126 cm = 18 cm.
Alex kept (7/19)·(1/3)·126 cm ≈ 15.47 cm.
Bob kept the longest part of the original wire.
Answer:
Triangle RED ≈ Triangle BUL
By-
SAS Congruencey
Beacause-
RE = BU (S)
ang RDE = ang BLU (A)
RD = BL (S)
(All the info for the relationship is given in the diagram itself)
Thus it's SAS Congruencey
Number 16- 216
number 17- 180
number 18- 252
We can use the arc length formula to solve this.
Arc length = 
Given arc length is 7 and radius is 5, we can plug in the values and solve for q.
ANSWER:
We can use the equation 
to find the value of q. And, the value of q is 80.21°.
