For this case we must simplify the following expression:

3 \frac {3} {4} -1 \frac {3} {14} =

To do this, we convert the mixed numbers to improper fractions:

\frac {4 * 3 + 3} {4} - \frac {14 * 1 + 3} {14} =\\\frac {15} {4} - \frac {17} {14} =\\\frac {14 * 15-4 * 17} {4 * 14} =\\\frac {210-68} {56} =\\\frac {142} {56} =\\\frac {71} {28} =\\2 \frac {15} {28}

Answer:

\frac {71} {28} = 2 \frac {15} {28}

180-90-38= 52 degrees or A
