Question

quick i need this answer. if one angle of a parallelogram is 4/5th of thd adjacent angle. find all the angles of the parallelogram​

Answer 1

let the angles be x and 4x/5 .

we know that x+(4x/5) =180° (they're co interior angles)

multiplying both sides by 5,

5x+4x=900°

9x= 900°

x=100°

so the two angles are 80° and 100°.
