The answer is A should be right
They both are acute angles
Use pitagoras
h^2=c^2+c^2
therefore
h=\sqrt{c^2+c^2}
Mikel carried the ball 4 1/2 yards. Let’s convert this: 9/2 yards (4*2+1), and if Fred carried it twice as far, that means he carried it 2 times 9/2. We know that 9/2 (or 4.5) * 2 is 9, so he carried it 9 yards.
It represents the product of two irrational numbers and is equivalent to rational number.
√3 and √12 are irrational numbers
But, √3×√12 =√36 = 6 which is rational. So your answer will be option A.
