Brendan's Scribepost for January 5, 2010.

13. Determine the length of the base of the large triangle. Express your answer to the nearest tenth of a millimetre.

c²-a²=b²

10²-8²=b²

(10x10)-(8x8)=b²

100-64=b²

36=b²

√36=√b²

6=b

The length of the base of the large triangle is 12 mm.

Nicely done Brendan! Your explanation was well thought out. I liked the pictures you put up and how you showed all your work. You also had a simple sentence answer which I liked.
