I'm doing this trig problem where it gives me a hypotenuse of 6, two missing legs, and a 40 degree angle, it wants me to find the measure of one leg (x), but I don't know what process I should go through. Should I use the Pythagorean theorem or should I use the fact that x/6( the hypotenuse) = the 40 degree angle? please help! |

#1 Guest depending where the angle is, as to how it relates to the sides, I would Feb 21, 2012 8:52:42 PMuse the sine, cosine, or tangent functions to find the unknown sides. | ||

#2 Guest take the sine of the angle times the hyp. this will give you the side opp. Rustynut "jus get n by " | +5 | |

moderator | #3 Melody You can't use pythagoras because you only have 1 side. So you have to use trig. depending on where you put the 40 degrees it could be cos or sin. See if this helps. http://www.mathsisfun.com/algebra/trig-finding-side-right-triangle.html | +5 |
