If A= -2 -8 -9 and B= 9 -9 6 find A-B-5 7 5. 2 -1 -3-4 -8 7. -4 -1 6

c. side angle side. u shares the same sides

m∠a is 90°

m∠b is 40°

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! )

it is a horizontal line.
