A pan of brownies is 7/10 full. Tyreese buys 2/5 of the brownies.

elixir [45]

Answer:

The answer to your question is below

Step-by-step explanation:

See the picture, please

In the first picture, we notice the initial amount of brownies (7/10), 7 brownies in a pan for 10 brownies.

After Tyreese bought 2/5 (7/10 - 2/5 = 3/10) there are 3 brownies left.

So in the picture, we notice only 3 brownies in a pan for 3 brownies.

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio $1:1:\sqrt{2}$ so we get

$u = v = 8$

We could have also gotten this using Trig:

$u = (8 \sqrt{2}) \sin 45^\circ = 8 \sqrt{2}/\sqrt{2} = 8$

$v = (8\sqrt{2})\cos 45^\circ = 8$

Or by recognizing u=v because remaining angle is 45 so this must be isosceles so

$u^2 + u^2 = (8 \sqrt{2})^2$

$2u^2 = 2 (8^2)$

$u = 8$
