A
use the graph of y=sec x to estimate the value of sec 165 degrees. round to the nearest tenth.
A. about -1
suppose you are building a rain shelter for a local park. the function y=4 cscO models the length y of rafters needed if the peak is 4 feet above the top of the wall. the angle O is formed by the rafters and the top of the wall. use a graphing calculator. find the length of the rafters needed to make the roof for O=19 degrees. round to the nearest tenth of a foot.
D. 12.3 feet
find the exact value. if the expression is undefined, write undefined. csc135 degrees
D. squared 2
evaluate sec3 pie /2 to the nearest hundredth. the angle is given in radians
undefined
