Answer:
[tex]The~measure~of~[/tex] ∠[tex]A~is=122[/tex]°
Step-by-step explanation:
[tex]To~determine~to~measure~of ~the ~unknown ~angle,~ be ~sure~ to ~use ~the ~total ~sum \\of ~180[/tex]
[tex]Then,~add~the~two~angles~and~subtract~them~with~180.[/tex]
[tex]You~should~be~getting~something~like~this:[/tex]
[tex]43+15=58[/tex]
[tex]180-58=122[/tex]
[tex]Thus,~the~measure~of~[/tex]∠[tex]A~is=122[/tex]°
[tex]Hope~this~helps~and~have~a~blessed~day~ahead![/tex]
