(3x + 5)° + (2x + 55)° = 180°
3x + 2x + 5 + 55 = 180
5x + 60 = 180
5x = 180 - 60
x = 120 ÷ 5
= 24°

If it is either a parallelogram or a rectangle, then, as they are adjacent angles, they add up to 180°.
Hence,
3x+5 + 2x+55 = 180 or,
5x + 60 =180;
5x = 180-60; [180-60=120]
x = 24°. [120÷5=24]
Hence, x = 24°
Hope you liked the answer. Please mark it as the brainliest. Thanks!
