11-76.

Use reference angles, the symmetry of a circle, and the knowledge that tan(20^{°}) ≈ 0.3640 to write three other true statements using tangent. Homework Help ✎

180° − θ reflects θ across the *y*-axis, so tan 160° = −0.3640

360° − θ reflects θ across the *x*-axis.

θ + 360° reflects θ across both axes.
