Question 1058013
Give "the angle" a variable, x.
{{{system(x+y=90,x+w=180,y/2=1+w/6)}}}



Review that system and be sure you understand it.  y is the complement of x and w is the supplement of x.   The equation using only the y and w is for the last part of the description.



Understood?  If no, keep examening until you do;  if yes, then:  Solve the system.
