Question 686181: Find the trigonometric value of angle Ө.
sec Ө=(5/2) and Ө in quadrant IV.
Thank you for help in advance, the quadrant portion is mainly throwing me off so help is appreciated. Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Find the trigonometric value of angle Ө.
sec Ө=(5/2) and Ө in quadrant IV.
cos Ө=1/sec Ө=2/5
using calculator and cos inverse function key:
cos Ө^-1(2/5)=293.58º or 5.12 radians in quadrant IV where cos>0
Ө would be 66.42º or 1.56 radians in quadrant I where also cos>0
