### Subject: Trigonometry

Using the Pythagorean Theorem, how are you going to find the measure of your adjacent side given your hypotenuse and opposite side?

From the original formula, c^2 = a^2 + b^2, derive the formula for adjacent: where: c = hypotenuse; a = adjacent; b = opposite 1. Transpose b^2 to the left hand of the equation. 2. That will make c^2 - b^2 = a^2. 3. Using the symmetric property of equality ( a = b then b = a), interchange the left hand and right hand of the equation. 3. That will make a^2 = c^2 - b^2. 4. Extract the roots of both hand of the equation. (square root since the exponent are 2) 5. That will make a (adjacent) = square root of (c^2 - b^2)

### Subject: Statistics

What is the difference between Statistics and statistic?

Statistics (with s) refers to the collection, analyzation and interpretation of data while statistic (without s) refers to the data gathered from the sample.

### Subject: Algebra

What is (2x^3) x ( -5x^6)?

1. Multiply the numerical co efficient: (2• -5) = -10 2. Since the variables are the same, copy it then add the exponents (Product Rule of Exponents) x ^ (3 + 6) = x^9 3. Rewrite the answer -10x^9
