A RHOMBUS HAS ONE ANGLE THAT MEASURES 40 DEGREES AND A PERIMETER OF 100 FEET WHAT ARE THE MEASURES OF THE REMAINING ANGLES

The opposite angles of a rhombus are equal, and the sum of the angles = 360 deg. Theefore, we have two 40deg angles and the other 2 are also equal.
360  (40 + 40) = 280 = sum of other 2
angles.
280 / 2 = 140 = measure of each of the
other 2 angles.
At = 40 + 40 +140 + 140 = 360.
