Question

If three angles of a quadrilateral are equal and the fourth angle is a right angle, then find the three angle of the quadrilateral​

Answer 1

Answer:

Then the three angles of the quadrilateral are 90 each

Answer 2

$< 1 = 90 \\\\let \ the \ 3 \ angles \ be \ x \\\\90 + x + x + x = 360\\\\3x = 360 - 90 \\\\3x = 270\\\\x = 270/3\\\\x = 90 \\\\all \ the \ angles \ of \ the \ quadrilateral \ are \ equal \\\\hope \ it \ helps \ !!!$
