there are 4 triangles
there are 9 circles
there are 8 squares
there are 4 rectangles
Answer:
a 2
b -1
Step-by-step explanation:
c
Set up a system of equations:
B=2+3C
B+C=90
The variable B is already solved, so plug into bottom equation:
2+3C+C=90
2+4C=90
4C=88
C=22
Plug C back in:
B+22=90
B=68
So B is 68 degrees and C is 22 degrees
