Answer:
Triangle 3: 3, 4 ,5
Step-by-step explanation:
Well, you can easily tell by 3, 4, 5 being a Pythagorean triple.
But you have to use the Pythagorean Theorem to solve this.
So you get the side lengths of the two shortest sides, and you add the squared versions of them together.
So: 3^2+4^2 and if that equals the biggest side:5^2 then it's a right triangle.

Answer:
Step-by-step explanation:
Hello, let's say that the price was P, a real number.
After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)
= P * 0.8
And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)
= P * 0.8 * 1.15
And this is equal to 22080, so
P * 0.8 * 1.15 = 22080
and the amount of the VAT is P *0.8 * 0.15
![=\dfrac{22080}{1.15}*0.15=2880](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B22080%7D%7B1.15%7D%2A0.15%3D2880)
Hope this helps.
Thank you.
