Question 778504
Half the supplement of an angle is 18 less than four times the complement of the angle. Set up and solve an equation to find the measure of the angle, the complement, and the supplement
let x= measure of the angle
supplement=180-x
complement=90-x
..
{{{(180-x)/2=4(90-x)-18}}}
LCD:2
{{{(180-x)=8(90-x)-36}}}
180-x=720-8x-36
7x=720-36-180
7x=504
x=72
180-x=108
90-x=18
measure of the angle=72º
supplement=108º
complement=18º
