Answer 1

a)

$\sf\huge {26}^{o} + {40}^{o} = {66}^{o} \\ \sf\huge {45}^{'} + {11}^{'} = {56}^{'} \\ \sf\huge {9}^{"} + {27}^{"} = {36}^{"} \\ \\ \large\boxed{{\sf \huge{66}^{o} \: \: {56}^{'} \: \: {36}^{"} }}$

b)

$\sf\huge {40}^{o} + {58}^{o} = {98}^{o} \\ \sf\huge {12}^{'} + {20}^{'} = {32}^{'} \\ \sf\huge {13}^{"} + {40}^{"} = {53}^{"} \\ \\ \large\boxed{{\sf \huge{98}^{o} \: \: {32}^{'} \: \: {53}^{"} }}$

c)

$\sf\huge {72}^{o} + {36}^{o} = {108}^{o} \\ \sf\huge {13}^{'} + {12}^{'} = {25}^{'} \\ \sf\huge {40}^{"} + {20}^{"} = {60}^{"} \\ \\ \large\boxed{{\sf \huge{108}^{o} \: \: {26}^{'} \: \: }}$

d)

$\sf\huge {75}^{o} + {16}^{o} = {91}^{o} \\ \sf\huge {23}^{'} + {30}^{'} = {53}^{'} \\ \\ \large\boxed{{\sf \huge{91}^{o} \: \: {53}^{'} \: \: {10}^{"} }}$
