The sides
12-3a
12-3a
4(2a-5)=8a-40
so for perimeter we + them
(12-3a)+(12-3a)+(8a-40)
=
2a-16
Answer:
see below
Step-by-step explanation:
We can name it by the vertex alone <Q
Or by three letters
<PQR or <RQP
Angle g would be congruent/equal to itself because of verticals angles theorem. i hope that helped a bit
Answer:
(0,20) (16,8) (8,4) so A
Step-by-step explanation:
