Answer:
b/4 +b + b-8 =73
2b + b/4 = 81
9b/4 = 81
9b =81 * 4
b = 9* 4
b = 36
The sides of the triangles are 9 inch, 28 inch and 36 inch respectively

Answer:
4.95 and 2.25
Step-by-step explanation:
x+y=7.2
x-y=2.7
Add equations
x+y + x-y= (2x-y+y)=2x
7.2+2.7=9.9
Therefore 2x=9.9 x=9.9/2=4.95
x=4.95
x+y=7.2
4.95+y=7.2
y=7.2-4.95=2.25
y=2.25
