Answer:
6 is the ans
Step-by-step explanation:
Write a Pythagorean triplet whose one member is.
2m, m 2 − 1 , m 2 + 1 \mathrm{m}^{2}-1,
mathrm{m}^{2}+1 m2−1,m2+1 is a Pythagorean triplet.
∴ (6, 8, 10) is a Pythagorean triplet.
If r and p are perpendicular:
1 + 2 = 90°
3 = 90°
4 + 5 = 90°
6 = 90°
If any one of these are true, r and p must be perpendicular
So if the necklace was $27 then we need to do 67.50-27=40.50, so that mans each of the bracelets cost $20.25.
