Given two vectors \( \mathbf{A}=-19.01 \mathbf{i}+5.87 \mathbf{j}, \mathbf{B}=6.95 \mathbf{i}-14.06 \mathbf{j} \), find the angle (in degrees) that the vector sum \( \vec{R}=\vec{A}+\vec{B} \) makes with the \( +x \)-axis, measured counterclockwise from that axis.
Express your answer in two decimal places.
