Question 1049066


Two angles are Complementary when they add up to {{{90}}} degrees (a right angle). 

if the angles are represented by {{{6x-3}}} and {{{12x + 20}}}, we have

{{{6x-3+12x + 20=90}}}......solve for {{{x}}}

{{{18x+ 17=90}}}

{{{18x=90-17}}}

{{{18x=73}}}

{{{x=73/18}}}

now find angles:

{{{6x-3}}} ->{{{6(73/18)-3}}}->{{{73/3-3}}}->{{{73/3-9/3}}}->{{{64/3}}}->{{{21.33333333333333}}}->{{{21.33}}}


and 

{{{12x + 20}}}->{{{2(73/3) + 20}}}->{{{146/3 + 60/3}}}->{{{206/3}}}->{{{68.66666666666667}}}->{{{68.67}}}


check:
{{{21.33+68.67=90}}}

{{{90=90}}}
