Asurveyor standing on a horizontal plain can see a volcano in the distance. the angle
of elevation of the top of the volcano is 23o
. if the surveyor moves 750 m closer, the
angle of elevation is now 37o
. determine the height of the volcano.

If 90° < θ < 180° and cotθ = -1/3, then cscθ =

Find the exact value of each of the following. in each case, show your work and explain the steps you take to find the value. (a) sin 17π/6 (b) tan 13π/4 (c) sec 11π/3

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
