The opposite angle is the same as the known angle. Each of the adjacent angles is the supplementary angle to the known angle. That is the pair add up to 180 degrees.
120
If it's a parallelogram then the other 3 angles are 75, 105 and 105 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
360
All angles of a parallelogram add up to 360 and opposite angles are always equal. Therefore 360 - 80 = 280 The other angles = 140 each Test 40 + 40 + 140 + 140 = 360
a parallelogram who's sides measure the same is called a rhombus :^>
A parallelogram has four sides. All four sided figures have a sum of the interior angle measures equal to 360°.
They are: 85, 95 and 95 degrees
It is 146 degrees.
120 square meters
Its other 3 angles are 37 degrees, 143 degrees and 143 degrees

If it's a parallelogram then the other 3 angles are 75, 105 and 105 degrees
The measure of D is 120.
105
The measure of A is 60.
