Can't without a picture :/
To solve this problem you must apply the proccedure shown below:
1- You must rewrite each value shown in the picture attached, in decimal form, as following:
6π-6=12.84
π^3=31
√99=9.94
2- Now, you can order the values from least to greatest:
√99
6π-6
π^3
The answer is:
√99
6π-6
π^3
This is an acute scalene triangle
The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees
The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.
