Answer: ABC seem to be equilateral
so A=B=C=60
D=42
E=35
F=35
G=55
H=45
I=45
j=15
k=15
L=75
M=180
N=11
O=35
P=11
Q=55
R=55
S=32
T=32
U=69
Step-by-step explanation:
21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
(8-7)/(-3-0)= -1/3
the slope is -1/3
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
