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°
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
one second let me work it out
okay so which trig function do you think you will need to use?
im not sure
i just need the answer
okay well i wont give you the answer but ill help you out, you need to use the trig function that contains all of the values that you are given and has only one variable (the one ou need to find AB)
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
`yep cos(60) = 8/x
Which expression shows the length of side AB? 8 cosec 60° 8 by sin 60 degrees 8 by cos 60 degrees 8 tan 60° so out of these it would be C?
is that how the answer choices are given to you ? in words?
okay well anyway solve for x in the equation you found and that should match one of the answers
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
