Question

what is the suplimentry angle of hundred degree

a) 40
b) 60
c) 80
d) 70​

Answer 1

$80 \: degree$

Answer 2

$180°-100°=80°$

$Two \: Angles \: are \: Supplementary \: when \: t hey \: add \: up \: to \:180 °. \\ \: These \: two \: angles \: (100° and \:80°) \: are \: Supplementary \: Angles, \: \\ because \: they \: add \: up \: to \: 180°$

$An  \: angle \:  measuring  \: 100° \: would \: be \:  supplementary \:  to \: \: any \\ \:  angle  \: measuring \: 80 °, \: but \: it \: cannot \: be \: called \: \\  supplementary \:  by \: itself. "Complementary" \: and \: "supplementary" \: are \: \\ terms \: that \: describe \: the \: relationship \: between \: two  \: angles. \: \\ They \: are \: comparative \: words \: like \: "larger."$

$So , option \: (c) \: 80° \: is \: your \: answer.$

$Hope \: this \: helps \: you!$
