plot(rand(3));
title('Angle=20^{\circ} - V=75{\km\per\hour}','Interpreter','latex');
lgd = legend('p1','p2','p3','Location','northwest','Interpreter','latex');

The legend function does not allow you to set the interpreter as one of the main arguments. You have to return a handle to it, and then use that to set the interpreter:
lgd = legend('p1','p2','p3','Location','northwest');
set(lgd,'Interpreter','latex')
