Answer:
2√3
Step-by-step explanation:
You recognize this as a 30°-60°-90° triangle, so you know the hypotenuse (R) is twice the length of the shortest side (√3).
The magnitude of R is 2√3.
_____
In case you haven't memorized the ratios for a 30°-60°-90° triangle, you can use trigonometry and the fact that ...
Sin = Opposite/Hypotenuse
sin(30°) = √3/R
R = √3/sin(30°) = √3/(1/2) = 2√3
Of course, doing this on your calculator will give a numerical answer, which you may not want.

Step-by-step explanation:
this is a quadratic equation, so use the quadratic formula: (-b+-√b^2-4ac) / 2a for ax^2+bx+c=0
ANSWER.
The correct answer is Option A
EXPLANATION.
The real number
to 9 decimal places.
You can see that the decimals are not repeating, neither will they terminate.
Therefore the real number is irrational because, the decimal does not terminate or repeat
Also note that,
.
That is,
is a product of two irrational numbers, which still gives an irrational number.
