Question

12. Find the measure of the supplement of
an angle of 65​

Answer 1

$\: \: \: \: \: \: \: \: \: \: \: one \: angle \: = 65°$

$\: \: \: \: \: \: \: \: another \: angle \: = x$

${sum \: of \: supplementary \: angles \: is \: 180°}$

$\: \: \: \: \: \: \: \: \: \: \: \: x + 65° = 180°$

$\: \: \: \: \: \: \: \: \: \: \: \: x = 180° - 65°$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 115°$
