Find the measure of each marked angle.
x = 25o, y = 125o
x = 20o, y = 25o
x = 20o, y = 35o
x = 35o, y = 20o
A lifeguard located 30 yd from the water spots a swimmer in distress. The swimmer is 40 yd from shore and 150 yd east of the lifeguard. Suppose the lifeguard runs, then swims to the swimmer in a direct line, as shown in the figure. How far east from his original position will he enter the water? (Hint: Find the value of x in the sketch)
8.1 yd
450 yd
64.3 yd
150 yd
If (1, -6) is on the terminal side of an angle θ in standard position, find sin θ, cos θ, and tan θ
Sin θ = √37/37, Cos θ = -6√37/37, Tan θ = -6
Sin θ = -6 , Cos θ = √37/37, Tan θ = -6√37/37
Sin θ = -6√37/37, Cos θ = √37/37, Tan θ = -6
Sin θ = -6√37/37, Cos θ = √37/37, Tan θ = 1/-6
If cos θ > 0 and cot θ < 0, what quadrant does θ terminate?

If cos θ = -3/5 and θ is in quadrant II, find the values of the other trigonometric functions of θ.
Sin θ = 4/5, Tan θ = 4/3, Csc θ = 5/4, Sec θ = 5/3, Cot θ = 3/4
Sin θ = 4/3, Tan θ = 4/5, Csc θ = 3/4, Sec θ = -5/3, Cot θ = 5/4
Sin θ = 4/5, Tan θ = -4/3, Csc θ = 5/4, Sec θ = -5/3, Cot θ = -3/4
Sin θ = 4/3, Tan θ = -4/5, Csc θ = 3/4, Sec θ = -5/3, Cot θ = -5/4
