Question

find the .measure of x ​

Answer 1

Answer:

$draw \: a \: line \: parallel \: to \: the \: other \: \\ line \\ so \: corresponding \: angles \: are \: equal \\ ie \: both \: are \: 100 \\ and \: by \: linear \: pair \: other = 80 \\ and \: sum \: of \: all \: angles \: of \: triangle \\ = 180 \\ so \: other \: angles + 80 + 15 = 180 \\ other \: angle = 85 \\ and \: \: \: x + 85 = 180 \\ x = 95$
