Find the measures of the interior angles This is what I did

48+x+(x-44)=180

48+x+x-44=180

4+x+x=180

4+2x=180

2x=180-4

2x=176

2x/2=176/2

X=88

And this is how I checked it
48+44+88=180

Can anyone correct me thanks

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
