For what values of x can this shape be a triangle? |

i suppose the right side is supposed to be the vertical one aye
uh lets see
pytagore thing = a^2+b^2=c^2
so this is a^2-c^2=b^2
now you go figure this out yourself |

dont like angles
nasty things, them |

@delta the answer doesnt require angles. Its a simple theorem. I just put mine in complicated terms to make sure its a brain teaser and not his homework.

ive never had it
im not sure if it works like this in other countries, but we have like 4 different kinds of math
there is math A, which is mostly stuff like chance things and i dont know
math C, which is a watered down version of A and basically for people who have trouble with math in general
math B, which is probably stuff like this, statistics and graphs and angles
and math D, which is hardmode+ and very few people actually do that |

simple geometry tells us that two of a triangles sides' added together can't be less than the other side
so 0 < x < 15 |

Simple addition and subtraction would tell you its 5 < x < 15, aka the range of 10cosx+5, or 10sinx+5, which ever you prefer

If it's 90° angle, then it is:
x²=5²+10²
x²=25+100 |√
x=√125
x≈11.18 |

(serious answer: x ~ 11.18) |

But x must the hypotenuse then. |

the triangle is not a right triangle
and I am not in trig so I have no idea what cos means |
