Help? I don't know what I'm doing wrong... Use the table for sine values, and find x to the nearest tenth. (My Answer) x (Approximately) = ? 1.0

    oh wait, i think i may know now, heres my work sin 48* = x/10 sin 48* = 0.7431 0.7431 = x/10 x = 10(0.7431) 0.1

    i hav instructions for the lesson and the definition they gave me for Sine ratio was: with respect to an acute angle of a right triangle, the ratio formed by the side opposite the acute angle over the hypotenuse.

    Okay, sin is opposite over hypotenuse. Sin 48= opposite/ hypotenuse. What's the opposite of sin 48?

    so that would be sin 48* = 10/x

    Exactly :)

    okay so the problem would be: sin 48* = 10/x sin 48* = 0.7431 0.7431 = 10/x 10 = x(0.7431) and then i divide?

    k i got 0.07431 so that goes to 0.1 when rounded right?

    i divided 0.07431 by 10 and i got 0.07431 and i rounded to the nearest tenth and since 7 is a high number i rounded it to 0.1
