180-105 = 75 degrees
It is 75 degrees
105
105 degrees Supplementary angles add up to 180 degrees.
If it's a parallelogram then the other 3 angles are 75, 105 and 105 degrees
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
It is 75 degrees
An impossibility because complementary angles add up to 90 degrees but if its a supplementary angle then 180-105 = 75 degrees
105
25 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
105 degrees Supplementary angles add up to 180 degrees.
It is 146 degrees.
180-105-32 = 43 The third angle measures 43 degrees
Alternate angles are equal and so angle b is also 105 degrees
If it's a parallelogram then the other 3 angles are 75, 105 and 105 degrees
180-105 = 75
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
