Question

Angle a and b are two adjacent angles of a parallelogram, if angle a=55 degree the angle b is ________ degree

Answer 1

Step-by-step explanation:

angles are 55, 55, (360 - 110)2 = 125, 125. Every two adjacent angles in a parallelogram add up to 180 deg and every two opposite ones are equal - so - if one is 55, the two adjacent ones are 125 degrees and the opposite one is 55.

Answer 2

Answer:

∠a=55 degrees

∠b=180-∠a

    =180-55

    =125 degrees.
