2. I think it is 12 days

To display exponents, use [sup][/sup]

For example,

2[sup]3[/sup]

will give

2³

2. Triangle ABC is such that AB=8, AC=9, and BC=10 cm. The bisector of the interior angle BAC intersects BC in a point M. What is the length of the segment BM? Give you r answer as a common fraction in lowest term.

These are tricky. I have worked on them for hours, and don't know what they are.

If anyone wants interesting problems tell me. ( I kow the answers to those )

1) uff, my minds running a bit of blank when it comes to absolute values. So I really dont think this is correct, but I got .1 and 0 for my answers. Checking them it works, but I still dont really know.

2) sorry broski, dont remember anything from geometry.

i had already gotten 1, and it's the same as yours

i need help on 2

Two equations would be (With BM as x and AM as y):
tan 90=y/x
y^2+x^2=8

Would that help?

Or the second equation could be y²+x
²=8, as Mr. Hui said earlier.
