Answer:

The measure of Angle A and B are;


\begin{gathered} m\measuredangle A=51^0 \\ m\measuredangle B=39^0 \end{gathered}

Step-by-step explanation:

Given that;

A ls 12° greater than the measure of B;


A=B+12\text{ ---------1}

The two angles are complementary;


A+B=90\text{ -----2}

Substituting equation 1 to 2, we have;


\begin{gathered} A+B=90 \\ (B+12)+B=90 \\ 2B+12=90 \\ 2B=90-12 \\ 2B=78 \\ B=(78)/(2) \\ B=39^0 \end{gathered}

Substituting B into equation 1:


\begin{gathered} A=B+12 \\ A=39+12 \\ A=51^0 \end{gathered}

Therefore, the measure of Angle A and B are;


\begin{gathered} m\measuredangle A=51^0 \\ m\measuredangle B=39^0 \end{gathered}
