I am a given preliminary to observe out for X, Y and Z. Right? So for that some of the trouble here. But before that let’south learn some basic concepts. Here’s soybean difficult riding a triangle straw hither, Riding rangel Automatic ratio. This is 90 is this T dog here the first I actually think this is uphold it is stable and his. Right. So nosotros have scientific discipline theater is equal to oppose information technology overhyped Dennis the worst affair to do next over hypotenuse and so theater they chosen to oppose information technology over at justice. So that’due south what we’re going to use the cinematic ratios to find out the solution for the given problem. We’ve got a strangle here struggling to run across so why not Ten. Right. So where do you use applies here to go for proverb do y’all practise You lot become four years time theatre sign 30 Right 7 30 Allow’due south oppose information technology. That is acts over Exchange three happiness right and so that is 1/2 or they will exercise acts over commutation fruit trees are from here we get Act is going to be equal to eight trees 823 Let me take gone. I wonder why and see we demand this this length here. We need to hear this length. Right? And then for that I’m going to use here now on same triangle what I’1000 going to use I utilize no crusade 30 so costs are equal to adjustments. And then I understand medico this is Cuban else here maybe and then mayhap it isn’t. And so a B Over we have happiness. That’southward xvi road three External routes of class 30 has given the states root three/2. That is equal to a b. over 16 road treat assaulting the swinger. A. B. Is equal to 16 route three time through three. Correct? All divided by two. Yes General 3 times and then three all divided by two. That’s gonna take to be 24. So 24 here, this is 24. The side by side part is I desire to find out why. And the right at this angle is 45. You lot know that the angles and belongings for triangle is 180 those 45. And so the unmarried would likewise be 45 because we have 45 plus 45 is 90 plus 90 is ane fourscore. I’m over again debating \$9 in holding we have used here. This is 45 45 to 45 plus 45 90 19 nineties when information technology was 45. And then at present we know that though in this triangle abc let’south say and the strangle nosotros have so the two angles are equal in the sight of a positive. That will be equal. This will be why this volition be equal to Y only. So it will exist why? That’s likewise why? And then nosotros accept the C. Is equal to Y. And what’south the next gnaw in solving this? So in crime of abc we desire to use the pythagorean triangle. Abc nosotros’re going to employ the despite the gorgeous to europe. Then if we use this term at present will have wide square, right? The white foursquare plus y squared Not equals 24 square. If you employ that Soul 2 White Square e Quilts 24 sq. So Yous start twice for equals 24 times 24. Frontward to Then 12 hither. So I will get Y squared equals 12 times 24. And then if I only backed priceless, so y squared is equal to Well is 2 times ii times three Times 24 is ii times two times two times 3. Right? And so what nosotros go hither, why is coming upwards to me to make a pair too? Times truthful times iii. And and so Route two. And then Why is coming upwardly to me to have a route to? So why is well road to? That ways these also coming out to be 12 to And then I and D. What are coming out to be Well, rule 2. Give thanks you.
