Answer:
(2,-3) and (4,5) 2.83 units
(3,-1) and (5,4) 5.39 units
(-5,7) and (8,5) 13.15 units
(-2,4) and (3,-1) 7.07 units
Step-by-step explanation:
there are 9461000000000 kilometers in a light year, aka 9.5 trillion
divide it by 2, you get 4730500000000
1 kilometer is more
X^+5x+8=0
x^2+5x=-8 kajvdvdhxjxjjxjxjxjxhx
90°
Angle C = arccos((84²+13²-85²)/(2×84×13))
= arccos(0/2184)
= arccos(0)
= 90°
