Answer:

solution,

$a. \: 17 \: cos \: p = 8 \\ cos \: p = \frac{8}{17} \\ sec \: p = \frac{1}{cos \: p} \\ \: \: \: \: \: \: \: = \frac{17}{8} \\ \\ b. \: sin \: p = \sqrt{1 - ( \frac{8}{17}) ^{2} } \\ \: \: \: \: \: \: \: \: \: \: = \sqrt{1 - \frac{64}{289} } \\ \: \: \: \: \: \: \: \: = \sqrt{ \frac{1 \times 289 - 64}{289} } \\ \: \: \: \: \: \: \: \: \: = \sqrt{ \frac{225}{289} } \\ \: \: \: \: \: \: \: \: = \sqrt{ { \frac{15}{ {17}^{2} } }^{2} } \\ \: \: \: \: \: \: \: = \frac{15}{17}$

Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image

saw5 [17]

Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

$\frac{hb}{2}$

h is height
b is base

Put in the values you know
$\frac{7 * 14}{2}$

Multiply

$\frac{98}{2} = 49$

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!

Identify the solution set for: −2|−2x−4|=−12

myrzilka [38]

Answer:

C: {−5, 1)

Step-by-step explanation:

Starting with −2|−2x−4|=−12, divide both sides by -2:

|−2x−4| = 6

Reduce this by dividing all terms by 2:

|-x - 2| = 3

This is equivalent to x + 2 = 3 and x + 2 = - 3

Solving thse two equations, we get x = 1 and x = -5

And so the solution set is C: {−5, 1)
