The measure of angles just is 56.9 find the measure of the complement and supplement of angle j

Yo bro this is simple. what you need to do is assess the vocabulary
complement=90 degrees
supplementary=180 degrees
so you use the number you were given and subtract it from the complement and supplement angles.
180-56.9=123.1 which is the answer to the supplementary of angle j
90-56.9=33.1 which is the answer to the complementary angle of j.

so 123.1 and 33.1

P.S- I might be wrong but use at your own risk

Gotta be d the music of previous eras
