Question

the adjacent angles of a parallelogram X and 2 X + 60 find all the angles of a parallelogram

Answer 1

We know that,

Sum of adjacent angles of paralellogram is 180°

=> x +2x +60 = 180

=> 3x = 120

=> x = 40


First angle = 40°

Second angle = 140°

Third angle = 40°

Fourth angle = 140°

Answer 2

$given \\ adjacent \: angle \\ are \: x \: and \: 2x + 60 \\ now \\ we \: know \: that \: \\ adjacent \: angle \: have \: sum \: 180 \\ so \\ x + 2x + 60 = 180 \\ 3x = 120 \\ x = 40 \\ 2x + 60 = 80 + 60 = 140 \\ and \: opposite \: side \: of \: parallelogram \: are \: equal \\ so \: \\ all \: angles \: are \\ 40......140.......40.......and140$
