Triangles PQR and LMN are graphed in the

x y

-plane. Triangle PQR has vertices P, Q, and R at

(5, 2)

(5, 4)

, and

(7, 2)

, respectively. Triangle LMN has vertices L, M, and N at

(5, 2)

(5, 4 + k)

, and

(7 + k, 2)

, respectively, where

k

is a positive constant.

If the measure of

∠ Q

t^{\circ}

, what is the measure of

∠ N

(90 - (t - k))^{\circ}

(90 - (t + k))^{\circ}

(90 - t)^{\circ}

(90 + k)^{\circ}
