Let ∠D be an acute angle such that cosD=0.33. Use a calculator to approximate the measure of ∠D to the nearest tenth of a degree

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.
