Question

If an angle is acute, an angle supplementary to it is (always,sometimes, or never) acute

Answer 1

Never, because it would have to be over 90° to be supplementary

Answer 2

suplementary is adding up to 180
acute means less than 90
so angle less than 90+something=180
is this something always, sometimes never acute
so
less than 90+less than 90=less than 180

so never
