Answer:
What is the perimeter of a rectangle that is 18 inches wide and 23 inches long?
P = 2(l+w)
l = 23, w = 18
P = 2(23 + 18)
P = 2(41)
P = 82
So the perimeter of the rectangle is 82 inches.
Hope this helped! Have a great rest of your day! :)
Choice A is correct
BC=DC
the two triangles share one angel C
the two triangles each have a right angle

I set x-3 and 3x-13 equal to each other and then got x equal to 5. So, I believe the correct answer would be C.) 5
