Answer
$73^o12'$
Work Step by Step
RECALL:
$1^o=60'$
Use the conversion rate above to obtain:
$\require{cancel}
73.2^0
\\= 73^0 + 0.2^o
\\=73^o + 0.2^o \cdot \left(\dfrac{60'}{1^o}\right)
\\=73^o + 0.2^\cancel{o} \cdot \left(\dfrac{60'}{1^\cancel{o}}\right)
\\=73^o + 0.2(60')
\\=73^o + 12'
\\=73^o12'$
