Answer:
45° 60° 64°
Step-by-step explanation:
Little triangle:180-(64+71)=45
Big triangle :180-(64+56)=60
A. parallelogram
B. I believe it'd be around (11.2,7.5)
C. √(10-5)^2+(9-4)^2 = 21, so yes they bisect
81-1= 80
80 / 2 = 40
D = 40
So:
40(2) = 81 - 1
The opposite of 1/3 = -1/3
the opposite of -7/12 = 7/12
