Hey there Smarty!
This would be considered to be a (acute angel) which in this case, we would have to make sure that this whole triangle would equal less than 270 because each angle would be less than
![90](https://img.qammunity.org/2019/formulas/mathematics/middle-school/xz9zuhwywhwbsjtbmcyydx5w5iwxv0ez09.png)
°
If we add/multiply
![\boxed{(90+90+90) \ or \ (90*3) = 270}](https://img.qammunity.org/2019/formulas/mathematics/high-school/tsfv2cancrvl3ole8evtwbk0olyf9bhecf.png)
.
So, we would have to know that was ever this would all add up to be, this would have to be less than 270°
![\left[\begin{array}{ccc}\boxed{\boxed{(2.5+5) \\ \\ (2.5*2.5) \\ (2.5-2) \\ (2.5-1) \\}} \\ \\ this \ would \ be \ why \ I \ would \ say \\ that \ this \ would \ be \ the \ answer \end{array}\right]](https://img.qammunity.org/2019/formulas/mathematics/high-school/zs81l0ejvhae5vkqde4fuwerw9fzfcitqa.png)
I truly hope this helps, and also, it's kind of my
first time doing this I hope this would be helpful.
