Find the area of the triangle

 

[tkhunny]

1) You really need to figure out how to make your attachments smaller.
2) You have a right triangle. Somewhere in your mind should pop up the words "Pythagorean Theorem".

If x is the missing piece of the goofy side, we have:

\(\displaystyle 5^{2} + (2+x)^{2} = 8^{2}\)

Now what?

Hello, valnadam!

\(\displaystyle \text{Find the area of }\Delta ABC.\)

    A *..
      | *:*.. 
      |   *:::*..
    5 |     *:::::*..
      |       *:::::::*..
      |         *:::::::::* 
      * - - - - - *  *  *  *  * 
                  B     2     C

You have a triangle with base 2 and height 5.

Where is your difficulty?

From what I can remember it is calculated as:

a=1/2*b*h
a=1/2*2*5
a=1/2(10)
a=5
