Answer 3

i need some help with geometry

Answer 4

Welcome to Openstudy!

Answer 5

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°

Answer 6

ask away

Answer 7

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

Answer 8

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

Answer 9

anyone?

Answer 10

one second let me work it out

Answer 11

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

Answer 12

im not sure

Answer 13

help

Answer 14

@heretohelpalways

Answer 15

@plzzhelpme

Answer 16

i just need the answer

Answer 17

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)

Answer 18

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

Answer 19

so what numbers would i use in this problem?

Answer 20

@Jdosio

Answer 21

the 8
the angle 60
and your variable Ab

Answer 22

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

Answer 23

the second choice i think

Answer 24

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

Answer 25

8/x

Answer 26

maybe

Answer 27

`yep
cos(60) = 8/x

Answer 28

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?

Answer 29

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

Answer 30

yes

Answer 31

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

Answer 32

thanks!

Answer 33

no probelm hope that helped:)

Answer 34

it did, thanks!

Answer 35

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

C WAS CORRECT
