Hint:

The sum of complementary angles are always equal to $90 to the power of ring operator.$

The correct answer is: 54

Explanation:

We have given different parts of $90 to the power of ring operator$ angle in terms of x .

We have to find the value of x .

We know that the sum of all these angles will be $90 to the power of ring operator$ . So, Using this we can easily find the value of x.

Step 1 of 1:
We have three parts of $90 to the power of ring operator$ angle as x,2x,2x
Now, we know that the sum of these angles will be $90 to the power of ring operator$ .
so,

$table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell x plus 2 x plus 2 x equals 90 to the power of ring operator end cell row cell 5 x equals 90 to the power of ring operator end cell row cell x equals 18 to the power of ring operator end cell end table$

Now the value of 3x will be

= $18 cross times 3$

$equals 54 to the power of ring operator$
