Castle Rock‚ walk x paces to the north‚ and then walk 2x - 4 paces to the east. If they share their information then they can find x and save a lot of digging. What is x? Given this scenario the Pythagorean Theorem would be the strategy we use to solve for x. I started off with the Pythagorean Theorem. I then plugged the binomials into the Pyth. Thrm. Next I moved (2+6)^2 to le left of the equation by subtracting (2x+6)^2 from both sides. I then squared the expression Next I foiled the expression

Pythagoras is commonly known for his discovery of the “Pythagorean Theorem”. The Pythagorean thereom states that the‚ “Square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides: c2 = a2 + b2” (Pyhtagorean…). Without Pythagoreas or his invention we would not

ANSWER: 8-4 Trigonometry Express each ratio as a fraction and as a decimal to the nearest hundredth. 1. sin A 3. cos A SOLUTION: The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. So‚ ANSWER: SOLUTION: The sine of an angle is defined as the ratio of the opposite side to the hypotenuse. So‚ 4. tan A ANSWER: 2. tan C SOLUTION: The tangent of an angle is defined as the ratio of the opposite side to the adjacent side. So‚ ANSWER: 3. cos A SOLUTION:

Lesson 1: Trigonometric Functions of an Acute Angle c a b C A B The ratios of the lengths of the sides of a right triangle are called the trigonometric ratios. For convenience‚ we will name the three sides and three vertices of the right triangle as‚ a‚ b‚ and c for sides and the A‚ B‚ and C for the vertices as shown in the figure: Sine (sin) Function of an acute angle of a right triangle is equal to the ratio of the length of the opposite leg to the length of the hypotenuse.

The ancient Greek civilization had many contributions that helped explain its significance in history. During the Archaic Age‚ there were many economies and cultures. One economy were the coins. Although‚ the Greeks did not invent coins they did use coins to their advantage. They improved the design of the coins and the circulation of them. The Greeks added stamps to both sides of the coins for identification and made them of silver (Dutton 48). The Greeks used the coins for “collection of taxes
