Here is a sketch of these angles:
∠1 and ∠2 are supplementary, meaning they add up to 180 degrees; therefore, we have
[tex]\measuredangle1+32^o=180^o[/tex][tex]\measuredangle1=180^o-32^o[/tex][tex]\textcolor{#FF7968}{\therefore\measuredangle1=148^o}[/tex]
∠2 and ∠3 are complematry, meaning they add up to 90 degree; therefore,
[tex]\measuredangle3+32^o=90^o[/tex][tex]\measuredangle3=90^o-32^o[/tex][tex]\textcolor{#FF7968}{\therefore\measuredangle3=58^o}[/tex]
Hence, ∠1 = 148° and ∠3 = 58°
