Question

What is the distance, in feet, between the tip of the tower A and a point C on the ground?



220 sin 46°



220 sec 46°

Answer 1

@jim_thompson5910 would it be the second one?

Answer 2

You're given the adjacent side and you want to find the hypotenuse. Agree?

Answer 3

use trigonometry
cos 46 = 220 / AC
AC = 220/COS 46
= 220 SEC 46 (as sec = 1/ cos)

Answer 4

yes @jim_thompson5910 so im right?

Answer 5

You are correct. This is because sec(x) is 1/cos(x)

So you're dealing with the adjacent and hypotenuse with sec(46) whereas the first one deals with the opposite side (which we don't have) and the hypotenuse
