Question

15 POINTS. One of the adjacent angles of a parallelogram is 20° more than the other. Find all the angles of the parallelogram. SPAMMERS AND GOOGLERS WILL BE REPORTED.​

Answer 1

Answer:

let the angles be x and x+20

since adjacent angles in a ||gm are co-interior

therefore, x + x + 20= 180°

2x= 180-20

x= 160/2

x= 80

angles= x = 80 and x+20= 100

since opposite angles of a ||gm are equal

therefore, all the angles are:- 80, 100, 80, 100

Answer 2

Step-by-step explanation:

let the smaller angle be X

then the adjacent angle will be (X+20)

therefore, X+X+20=180°

(sum of two adjacent angles of //gm =180°)

2x=180-20

2x=160°

X=80°

and X+20=100°

since opposite angles of //gm are equal

.....therefore all angles of the //gm are

80°,100°,80°,100°

hope this will help you
