x equals 9.
The largest angle is 90.
Step-by-step explanation:
![10x + 3x + 7x = 180 \\ \frac{20x}{20} = \frac{180}{20} \\ x = 9](https://tex.z-dn.net/?f=10x%20%2B%203x%20%2B%207x%20%3D%20180%20%5C%5C%20%20%20%5Cfrac%7B20x%7D%7B20%7D%20%20%3D%20%20%5Cfrac%7B180%7D%7B20%7D%20%20%5C%5C%20x%20%3D%209)

(<em>s is a side length)</em>
<em>24 = </em>
=
= <em>s</em>
= <em>s</em>
<em>2</em>
= <em>s</em>
When it says x and y are directly related it means that x is multiplied by something to get y. To solve you divide y by x which is 840 divided by 6. Which is 140 then you multiply and solve so the y value for 5 is 700. The x value for 420 is 3 and the y value for 4 is 560.
