7. Lines ℓ and m intersect at point P and are perpendicular. If a point Q is reflected across ℓ and then across m, what transformation rule describes this composition? 8. A triangle is reflected across line ℓ and then across line m. If this composition of reflections is a translation, what is true about m and ℓ?

.95

step-by-step explanation:

answer: (-6,3)

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! )
