Trigonometry

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify

We are given a right triangle. We can use PT to solve for the missing length a.

Step 2: Define

hypotenuse c = 15

leg b = 9

leg a = ?

Step 3: Find missing length a

Substitute in variables: a² + 9² = 15²
Isolate a term: a² = 15² - 9²
Exponents: a² = 225 - 81
Subtract: a² = 144
Isolate a: a = ±12

Since we are not dealing with a quadrant triangle, we can disregard the negative root of the quadratic.

∴ a = 12 is our final answer.

Answer:

Step-by-step explanation:

The room is rectangular, so the two walls and the diagonal (distance between opposite corners) form a right triangle.

We can use $a^2 + b^2 = c^2$ to compute the other wall's length:

$13^2 = 12^2 + x^2\n169 = 144 + x^2\n25 = x^2\nx = \pm 5$

A baker is calculating the charge for two types of cookies. What formula tells the cost, in dollars, if chocolate chip cookies are $1.50/dozen and lemon frosteds are $2.50/dozen? Let c = number of dozens of chocolate chip cookies; L= number of dozens of lemon frosteds; T= total charge

Answers

c=1.50 * 12 = 18.00$
L=2.50 * 12 = 30.00$
18.00 + 30.00 = 48.00
T=48.00$

Jovante decides to start a business by making buttons and selling them for 25 cents each. The button machine costs $125 and the materials for each button cost 10 cents.

Answers

If he wants to sell buttons, say 40 buttons, he will get a profit of 1000 cents. And one dollar is equal to 100 cents so he only earns 10 dollars. However, the costs for the machine are 125 dollars. Therefore he has a loss of 115 dollars.
