ughh...angle bisector.
how could I not notice that?
2006-06-07 14:50:05 · update #1
The bisector of the angle will divide the opposite side into line segments that are proportional to the lengths of the sides.
Therefore,
x/9 = (7-x)/5
Cross multiplying
5x = 63 - 9x
14 x = 63
x = 9/2 = 4.5
Hope that helps.

The hypotenuse is 9 the formula for the base is 1/2 hypotenuse, so 9 /2 = 4.5

Notice the angle bisector. It means that...
5/(7-x)=9/x
5x=63-9x
14x=63
x=4.5
Also, to the last answer, this isn't a right triangle, so there is no hypotenuse.
