A. The square of an irrational number \sqrt(11)=\sqrt(11)*\sqrt(11)=\sqrt(11^2)=11, which is a rational number. However, in B, C, and D, the two pair of rational numbers cannot multiply to become a rational number.

Answer: option A.        \sqrt{11} . \sqrt{11}

Justification:

By definition the product of the square root of a number times itself is the same number.

This is:     \sqrt{n} . \sqrt{n} = n


Because:    \sqrt{n} . \sqrt{n} =( \sqrt{n})^2 = n


Therefore, for the case given:   \sqrt{11} . \sqrt{11} = 11

And you have proved that the product of the two irrational numbers, √11, is a ratonal number, 11.

On the other hand, the other products, B, C, and D do not yield to a rational number. The result of the products shown on B, C, and D are irrational.

What is the measurement of angle a?
Illusion [34]
Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25

Hence, angle a = 3(25) - 10 = 65°
