    if tan = 3 then that means opposite side is 3 and adjacent side is 1. make sense?

    i think so it's one because on the unit circle the radius is one i guess? that's how i'm thinking about it

    no.. that's actually because \[\tan = 3 = \frac 31 = \frac{opposite}{adjacent}\] so opposite side is 3 and adjacent side is 1

    good so that means hypotenuse is \[\huge \sqrt{3^2 + 1^2}\implies \sqrt{9 + 1} \implies \sqrt {10}\] right?

    \[\sec = 4 = \frac 41 = \frac{hypotenuse}{adjacent}\] so that means hypotenuse = 4 and adjacent = 1 right?

    the hypotenuse is 4 and the adjacent angle is 1?|dw:1347253071421:dw|

    now....use pythagorean theorem \[\huge a^2 + b^2 = c^2\] \[\huge \implies a^2 = c^2 - b^2\] \[\huge \implies a = \sqrt{c^2 - b^2}\] got it?

    0.8 means 8/10
