Question

Find each angle of a parallelogram if two consecutive angles are in the ratio 1:3.​

Answer 1

$\huge \color{cyan} \boxed{ \colorbox{black}{AnsWer}}$

$some \: of \: adjacent \: angles \: \\ of \: parallelogram \: is \: 180 \: degree. .$

$so.. let \: no \: be \: x$

$x +3x =180$

$4x =180$

$x=180/4$

$= 45 \: degree$

$so.. \: one \: angle \: is \: 45$

$other \: one \: is \: 3 \times 45=135$

$the \: opposite \: angles \: of \: \\ parallelogram \: are \: equal$

$so..\: angle \: opposite \: to \: \\ 45 \: will \: be \: of \: 45 \: degree..$

$and \: opposite \: to \: 135 \: \\ will \: be \: of \: 135 \: degree$
