lol hi

okay well welcome! do you have any math problems you want help with?

i need some help with geometry

Welcome to Openstudy!

The picture below shows a right-triangle-shaped charging stand for a gaming system:
The side face of a charging stand is a right triangle labeled ABC. The measure of angle ACB is 90 degrees and the measure of angle ABC is 60 degrees. The length, BC, of the side adjacent to the angle ABC is 8 inches.
Which expression shows the length of side AB?
8 cosec 60°
8 by sin 60 degrees
8 by cos 60 degrees
8 tan 60°

ask away

if u need help....just post the questions and people will start to help u..........

any ideas on what this answer would be? i think the last one, but just a guess

anyone?

one second let me work it out

okay so which trig function do you think you will need to use?

im not sure

help

i just need the answer

e.g. sin(angle) = opp/hyp
cos(angle) = adj/hyp
tan(angle) = opp/adj

so what numbers would i use in this problem?

the 8
the angle 60
and your variable Ab

so which trig function uses the angle (hint all of them us an angle)adjacent and the hypotenuse

the second choice i think

yes cos perfect so now plug in all the values you know into the cos function

8/x

maybe

`yep
cos(60) = 8/x

is that how the answer choices are given to you ? in words?

yes

okay well anyway solve for x in the equation you found and that should match one of the answers

thanks!

no probelm hope that helped:)

it did, thanks!

A. 8 cosec 60°
B. 8 by sin 60 degrees
C. 8 by cos 60 degrees
D. 8 tan 60°
C WAS CORRECT
