Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,  , is given by:
, is given by:
![G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}](https://tex.z-dn.net/?f=G%20%3D%20%5Csqrt%5Bn%5D%7Bn_1%20%5Ctimes%20n_2%20%5Ctimes%20...%20%5Ctimes%20n_n%7D)
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
- Two elements(n = 2), a and 34.
 
Thus:

We find the square of each side, so:


Simplifying both sides by 17:



The value of a is 18.

Answer:
√a^3−7-4
Step-by-step explanation:
Replace all occurrences of + − with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ −1= −1
 
        
             
        
        
        
Answer:
C 
Step-by-step explanation:
The sum of the angles is 90 
2x + x = 90 
3x = 90 
x = 30 
the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees
