we find that the slope is (0-3)/(-8-0) so it is -3/-8=3/8 and we have 3/8*2=3/4 so it is (3/4,5) and t=3/4
so we have 3+4+7=14 for all the ratios of the angles then we do 180/14=90/7 for each unit of the ration then we have 90/7*3,90/7*4,90/7*7 for the angles so the angles are 270/7o,360/7o,90o
9 since 3^2=3*3=9 so a=9
LOL so funny
But what's an elaborate number?
Translated:
Why 1 is not considered an elaborate number? After all, its only divisor is 1, and the sum is 1
oops I divided but it was supposed to be multiplied thanks Guest
