    Question 1

    Two circles intersect each other on points x and y. P and Q are centre points. The radius of circle P is 6 cm and the radius of circle Q is 7cm. The length PQ = 9cm, work out the area of triangle PXQ.

    First person with the correct answer and clear steps of what they did wins $10T.

    No, no , no, no!

    This isn't my homework don't worry, I just saw this section and thought that I would come up with some kind of game.

    I am very good at math and made that question up so yeah.

    (Please delete above posts).

    The question is impossible since there is no image of this question. Instead, we have no clue of where X and Y could possibly be. That is the correct answer btw.

    I can't even draw out my answer because the question is so vague. And since this is a homework question, you want us to do your homework. @Shavon

    Dude can you stop spamming and complaining, keep it all in one post - that's a warning.

    It is possible and it's not supposed to come with a image. If you can't do it then don't say anything.

    Also, it's not my homework, it's just a math question.

    If you like a hint, ask me DM me on the website and I'll get you started.

    I am not spamming if there is only 2 replies. Nothing repeated much.

    Ah, you see you can't really work it out if I forgot how I did it since this was done by the human brain. I just want to know if it was correct or not.

    Hey Guys,

    So @EukalyptenHD recently challenged me to try his math question. I guess he thought I couldn't solve it and to be honest, I didn't think I could either, but here is my try and I hope its right :p

    Edit. Okay so I guess at the time of posting this the forums doesn't like the link provided for the image so here is the like https://imgur.com/a/RJbI1

    Your answer is wrong.

    Keep in mind that you can't use Pythagoras to work out the height since it's not an isosceles triangle. One of its sides is 6cm and the other is 7cm meaning that if you split it in half, it doesn't give you 4.5cm (9 / 2).

    This goes to you as-well @wsyd69.

    Everyone, you have until Friday to post your answer!

    Good luck.

    So using a different method to work out the Area I found out I was only a few decimals off the answer. The method I used to work this out was the Semi-Perimeter method which in turn gave me this answer. In the image, it shows how to do this step by step.

    My answer, in short, was 20.97cm squared.
