What are the choices. I need them in order to answer with the best/correct answer.
Check the picture below.
recall that a flat-line is always 180°, also recall that all interior angles in a triangle are 180°, therefore
x + 95 + 54 = 180. Surely you'd know what "x" is.
Answer:
9 inches
Step-by-step explanation:
Perimeter of equilateral triangle = 3x
Perimeter of square = 4x
3(x + 6) = 9 + 4x
3x + 18 = 9 + 4x
-x = -9
x = 9
