Instructions: Use the ratio of a 30-60-90 triangle to solve for the variables.

Pepsi [2]

Answer:

$x=20$

$y=10\,\sqrt{3}$

Step-by-step explanation:

In the triangle we have the following trigonometric equations:

$tan(60^o)=\frac{opposite}{adjacent} \\\sqrt{3} =\frac{y}{10} \\y=10\,\sqrt{3}$

and also:

$cos(60^o)=\frac{adjacent}{hypotenuse}\\\frac{1}{2} =\frac{10}{x}\\x=20$

Frosty Whip Inc. budgets 65 percent of its total expenses for marketing. Total expenses for the company this year are $500,000.

Misha Larkins [42]

65% of the total expenses is for marketing, in which 500,000 is the total.

First, change the percentage into decimal

65% = 65/100 = 0.65

Next, to find the amount budgeted for marketing, multiply the total with the decimal

0.65 x 500000 = 325000

$325000 is used for marketing
