For a shape to be a square all the angles need to be 90 degrees.
Angle B = 3x+60 = 90
3x +60 = 90
Subtract 60 from each side:
3x = 30
Divide both sides by 3:
x = 30 /3
X = 10
The answer is 170 centimeters.
The prefix centi means 100. If you want to convert meters to centimeters, simply multiply by 100! For converting centimeters into meters, just divide by 100. Good luck, hope this helps!
