Question

two consecutive angkes of a parallelogram are (x+60)° & (2x+30)° what special name can you give to this parallelogram​

Answer 1

I think that it can be a rectangle cause

x+60+2x+30=360

3x+90=360

3x=360-90

3x=270

x=90

(all the angles of a rectangle measure 90° & it can't be a square as the sides of a square are of equal length)
