If you know the measure of one of the base angles of the triangle, how do you find out the measure of the other base angle?

Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle. tiles : cosb sinb tanb sincposs matches: c/b b/a b/c c/a

Given that sin∅ = 1/4, 0 < ∅ < π/2, what is the exact value of cos∅? a. (√4)/4 b. (√15)/4 c. (4π)/2 d. (4√2)/4

The area (in square feet) of an x-foot-wide sidewalk can be modeled by y=-0.002x^2+0.006x. what is the width of the sidewalk to the nearest foot?
