Scalene just means all the angles are different. Not particularly helpful; we'll check at the end.
Obtuse is bigger than 90, so this will be the biggest angle in the triangle, let's call it A. A>90 degrees.
B=56 degrees.
C is the smallest angle. It will be smaller than B, since A is obtuse.
The two equations we can write are
A = 3C
A+B+C=180
3C + 56 + C = 180
4C = 124
C = 31
A = 3(31) = 93
Check:
31 + 93 + 56 = 180, good
all three different, scalene, good
93 is obtuse, good
Answer: Triangle has angles 31°, 56°, 93°
Sure,I do not agree because the answer is -20>-27
By using exponent properties, we will get the simplified expression:
![x^{-1}*y^{1/2}*z^2](https://tex.z-dn.net/?f=x%5E%7B-1%7D%2Ay%5E%7B1%2F2%7D%2Az%5E2)

How to simplify the given expression?</h3>
Here we have the expression:
![(x^{1/2}*y^{-1/4}*z)^{-2}](https://tex.z-dn.net/?f=%28x%5E%7B1%2F2%7D%2Ay%5E%7B-1%2F4%7D%2Az%29%5E%7B-2%7D)
Remember the exponent properties:
![(a^n)^m = a^{n*m}](https://tex.z-dn.net/?f=%28a%5En%29%5Em%20%3D%20a%5E%7Bn%2Am%7D)
And:
![(a*b)^n = (a^n)*(b^n)](https://tex.z-dn.net/?f=%28a%2Ab%29%5En%20%3D%20%28a%5En%29%2A%28b%5En%29)
So using these two properties, we can rewrite:
![(x^{1/2})^{-2}*(y^{-1/4})^{-2}*(z)^{-2}\\\\(x^{-2*1/2})*(y^{-2*-1/4})*(z^{-2}})\\\\x^{-1}*y^{1/2}*z^2](https://tex.z-dn.net/?f=%28x%5E%7B1%2F2%7D%29%5E%7B-2%7D%2A%28y%5E%7B-1%2F4%7D%29%5E%7B-2%7D%2A%28z%29%5E%7B-2%7D%5C%5C%5C%5C%28x%5E%7B-2%2A1%2F2%7D%29%2A%28y%5E%7B-2%2A-1%2F4%7D%29%2A%28z%5E%7B-2%7D%7D%29%5C%5C%5C%5Cx%5E%7B-1%7D%2Ay%5E%7B1%2F2%7D%2Az%5E2)
So we conclude that the completely simplified expression is:
![x^{-1}*y^{1/2}*z^2](https://tex.z-dn.net/?f=x%5E%7B-1%7D%2Ay%5E%7B1%2F2%7D%2Az%5E2)
