Finally, a teacher who understands that, you won't get work from students till you get into their shoes. What i mean is you weren't to lazy to use more advanced questions intead of those boring, and uneducational one digit questions. YOU JUST KILLED TWO BIRDS, WITH ONEEE STONE. THANKYOU! Please keep it up, because not all teachers do, for its like trying to cook your own food: you have to prepare it, clean it, figureout you craving, then start to work you way out with time, which you constantly have to work with.

I did learn from my boss that a 3,4,5 triangle is old farmers triangle, ccause farmers didn't have calculators ,just measuring tape so they would pull 30' over set point then intersect that point with one extending from other point 40'with 50' and they could build their fence seprating their property at a 90^ from the road.

For a 45-45 what if the hypotenuse is just 7? How do I find out what the other sides are

[@MrHelpfulNotHurtful]

This video will show you why the answer is 7/root2: kzbin.info/www/bejne/poPCe2icmqmWe68

[@kpmann8775]

I might be late on this question but what do you do if your 45,45-degree triangle has a hypotenuse of 9 or something

[@MrHelpfulNotHurtful]

Let's call the hypotenuse h and let's call the leg x. The hypotenuse always equals the leg times radical 2. So we have the equation h=x (radical 2). If the hypotenuse is 9, the equation becomes 9 = x (radical 2). To solve for x you divide both sides by radical 2. You get x = 9/(radical 2).

[@dhruvabarua5265]

Can you explain how things would work if the 60 degree angle was at the top while 30 at bottom? I heard it is different that way and you have to multiply the hypotenuse by radical 3.

[@MrHelpfulNotHurtful]

Rotating the triangle so the 60 is at the top changes nothing. All the same rules apply. At 11:43 (and other places in this video) there is an example with the 60 at the top. I can find you more examples if you need them.

[@dhruvabarua5265]

Thanks for the reply but I meant how what if 60 was switched with 30 in that example. Like if you completely switch the angles around not rotate. I watched a video from yaymath about it and thought it had some sort of change to the formula.
