Plz give the working out and tell what a complement and a supplement is. i have absolutely no idea what supplement and complement is so plz explain it well. thanks
i mean wot does supplement and complement mean. i know that complimentary adds up to 90 and supplementary adds up to 180
okay i get it now. i worked it out deifferents though..... but thanks for da help!
X+Y=90
X+Z=180
Y=0.25Z
X+0.25Z=90

simultaneous equations.....
X+0.25Z=90
X+Z=180
0.75Z=90
Z=120

X+Z=180

Therefore X must equal 60 degrees. is that a good way of workin' it out?

and btw i kno i suck at maths cuz im only 11!!!!!!!
