Harry needs 212121 square meters of fabric for every 666 wizard cloaks he makes.

answer: i guess 105 degrees?

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
