ILL MARK AS BRAINLIEST!! AND GIVE 10 POINTS!!! Are the following lines parallel, perpendicular, or neither?
Licemer1 [7]

Answer:

b perpendicular

Step-by-step explanation:

all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites

Line 1)      -7 -8 / -3 -2  X= 3X

Line 2)      -3 - 0 / 12 - 3  X = -1 / 3X

Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.

Can someone step by step explain the answer please
Vinvika [58]

Answer: z = \sqrt{10}

Step-by-step explanation:

To find <em>z</em>, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

\frac{a}{x} =\frac{x}{b}

You can use <em>5</em> as <em>a</em> and <em>2</em> as <em>b</em> to complete the proportion:

\frac{5}{z} =\frac{z}{2}

Next, to solve:

<u>Step 1</u>: Cross-multiply.

\frac{5}{z} =\frac{z}{2}

(5)*(2) = z*z

10 = z²

<u>Step 2</u>: Take square root.

10 = z²

√10 = z

I hope this helps!
