Which of the following is true about the right triangle?
katrin2010 [14]

Option 1. cos (a) = \frac{3}{5}, option 3. sin (a) = \frac{4}{5}, and option 5. tan (a) = \frac{4}{3} are true about the right triangle.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here the hypotenuse measures 15 units. Assume the other side measures x.

15^{2} = x^{2} +9^{2} , x^{2} = 15^{2} -9^{2} .

x^{2} = 144, x= 12.

Step 2:

sin \theta = \frac{oppositeside}{hypotenuse} ,cos \theta = \frac{adjacentside}{hypotenuse} , tan \theta = \frac{oppositeside}{adjacentside}.

For angle A, the opposite side is 12 units long, the adjacent side is 9 units long and the hypotenuse is 15 units long.

sin (a) = \frac{12}{15} ,cos(a) = \frac{9}{15} , tan(a) = \frac{12}{9}.

sin (a) = \frac{4}{5} ,cos (a) = \frac{3}{5} , tan (a) = \frac{4}{3}.

So option 1. cos (a) = \frac{3}{5}, option 3. sin (a) = \frac{4}{5}, and option 5. tan (a) = \frac{4}{3} are true about the right triangle.

A $649 laptop computer cost $519.20 after a coupon is applied. What percentage off is the coupon?
Nadya [2.5K]

Answer: 20%

<em>Step by Step Explanation: </em>

<em>Start by subtracting 519.29 from 649, you would get 129.8</em>

<em>Then take 129.8 and divide that by 649.</em>

<em>You get 0.2 which equals 20%</em>

<em>Tip: To find the percent of a fraction you divide the numerator by the denominator. For example, if you want to find the percent on a test, and you get a 8/10 you just divide 8 by 10. Which obviously equals 80.</em>
