Problem 7. Let T be the left-shift operator on R^n. Compute the adjoint of T. (Hint: To check that (Tu, v) = (u, T*v) for all u, v ER^n, it suffices to
check (Tei, ez) = (ei, T*e;) for all i, j.)

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
