NEED TO KNOW:
BY DEFINITION THE SUM OF SUPPLEMENTARY ANGLES IS 180 DEGREES!
S%5B1%5D%2BS%5B2%5D=180
THE QUESTION STATES THE FOLLOWING TO BE TRUE:
S%5B1%5D=+2%28S%5B2%5D%29%2B3
SUBSITUTE
%282%28S%5B2%5D%29%2B3%29%2BS%5B2%5D=180
{SOLVE:
2%28S%5B2%5D%29%2B3%2BS%5B2%5D=180
COMBINE
%283%28S%5B2%5D%29%2B3%29=180
SIMPLY: SUBTRACT 3 FROM EACH SIDE OF THE EQUATION
3%28S%5B2%5D%29=177
DIVIDE EACH SIDE OF THE EQUATION BY 3
S%5B2%5D=59 THE MEASURE OF THE ANGLE!!
S%5B1%5D=+2%2A59%2B3
S%5B1%5D=+highlight%28121%29 THE MEASURE OF THE ANGLE IN QUESTION
CHECK YOUR ANSWER!!
59-121 = 180
