Answer:

[tex]\large\boxed{4a^o+4b^o=360^o}\\\boxed{2(a^o+b^o)=180^o}\\\boxed{a^o=90^o-b^o}[/tex]

Step-by-step explanation:

[tex]4a^o+4b^o=360^o\qquad\text{divide both sides by 2}\\\\2a^o+2b^o=180^o\qquad\text{distributive}\\\\2(a^o+b^o)=180^o\qquad\text{divide both sides by 2}\\\\a^o+b^o=90^o\qquad\text{subtract}\ b^o\ \text{from both sides}\\\\a^o=90^o-b^o[/tex]
