How do I work out the Height of this triangle if I know all sizes?

kwikbreaks

I got this wrong...

Don't want to appear cheeky here, but this is gonna come up more often. Is there anybody who would be kind enough to write me a small excel file and mail it to me with the formula already input, so I just have to input the following:

Side A (Left side)
Side B (Right side)
Bottom line

I hope someone will be kind enough...

Are you aware that your second triangle isn't right angled though?

Cut the triangle in half (in the middle) and call that side d, this makes it into a right-angled triangle. Apply pythagoras's..

So, Hypotenuse (side opposite the right angle) = a =1435 mm
Other side = c/2 =2030mm = 1015 mm

Making the other side (d) = 1014.39636 mm or 1014.4 mm to 1 dp

Interesting to note that the angles on your triangle are 90º, 45º and 45º.

Why are you lot doing someones' homework?


It is not as if someone hasn't already given them the complete workings out & theory so all the need to do is substitute numbers & use a calculator....
