if you decrease by a given percent and then increase by the same percent, will you be back where you started? how do you know
quester [9]

Lets pick a random number, like 50. Lets decrease and increase it by 50%. After the decrease, you will get 25, but when you increase it by 50%, it's only 37.5. No, because when you decrease it, you have a smaller base, so it increases less than it decreases. 50% of 100 is 50, but 50% of 50 is 25. You can see there is a significant difference.

In the above triangle, if x = , y = 1, and z = 2, then which of the following is equal to tan(60°)?
vesna_86 [32]

Answer: Option A

tan(60\°) = \sqrt{3}

Step-by-step explanation:

We know the sides and z. So since it is a straight triangle we use the Pythagorean theorem to pull the length of the x side.

z ^ 2 = x ^ 2 + y ^ 2\\\\x^2 = z^2 - y^2\\\\x=\sqrt{z^2 - y^2}\\\\x=\sqrt{2^2 - 1^2}\\\\x=\sqrt{4 - 1}\\\\x=\sqrt{3}

By definition, the tangent of an angle is:

tan(\theta) = \frac{opposite}{adjacent}

In this case:

adjacent = y=1\\\\opposite=x =\sqrt{3}\\\\\theta=60\°

Then:

tan(60\°) = \frac{\sqrt{3}}{1}

tan(60\°) = \sqrt{3}
