Mathematics
1 answer:

Answer:

x = \sqrt{6} , y = 2\sqrt{3}

Step-by-step explanation:

using the tangent ratio and the exact value tan45° = 1 , then

tan45° = \frac{opposite}{adjacent} = \frac{x}{\sqrt{6} } = 1 , then

x = \sqrt{6}

----------------------------------

using the cosine ratio in the right triangle and the exact value

cos45° = \frac{1}{\sqrt{2} } , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{\sqrt{6} }{y} = \frac{1}{\sqrt{2} } ( cross- multiply )

y = \sqrt{6} × \sqrt{2} = \sqrt{12} = 2\sqrt{3}

I think the answer is C. "He made a place value error when dividing. If he would have divided 1.09 by 8, he would have found the price of each individual pen.
