Question

say the proper answer 87°​

Answer 1

Step-by-step explanation:

supplementary angle = 180°

so,

87° + x = 180°

x = 180° - 87°

x = 93°.......

Answer 2

$\sf{Let \: the \: supplement \: of \: the \: angle \: be \: measure \:} \mathbb {x° } \\ \sf{The \: sum \: of \: measures \: of \: two} \\ \sf{ \: supplementary \: angles \: is \: 180°} \\ 85 + x = 180° \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 180 - 85 \\ ⠀⠀⠀ \boxed{ \mathfrak{x = 95°}} \\ \sf{ \therefore The \: measure \: of \: the \: supplement } \\ \sf{\: of \: an \: angle \: of \: 85° \: is \: 95°.}$
