CPM Homework Help : A2C Problem 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.

Hint:

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

Hint 2:

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

More Help:

θ + 360° reflects θ across both axes.
