Question

If two angles of a quadrilateral are 40° and 110° and the other two are in the ratio
3:4, find these angles.​

Answer 1

$answer \\ \\ two \: angles \: of \: triangle = 40 \: and \: 110 \\ \\ let \: the \: other \: two \: angle \: be \: 3x \: and \: 4x \\ \\ since \: sum \: of \: all \: angles \: of \: quadrilateral \: i \: 360 \\ \\ 40 + 110 + 3x + 4x = 360 \\ = > 150 + 7x = 360 \\ = > 7x = 360 - 150 \\ = > 7x = 210 \\ = > x = 30 \\ \\ \\ hence \\ \: \: \: \: \: other \: two \: angle \: is \: 3 \times 30 = 90 \: and \: 4 \times 30 = 120 \\ \\ \\ \\ mark \: me \: as \: brainlist$
