    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°

    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

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

    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?

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

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