Find the value of x that verifies that l ⊥ m.
Genrish500 [490]

Answer:

X= 12

Step-by-step explanation:

Simplifying

4x + -2 = 46

Reorder the terms:

-2 + 4x = 46

Solving

-2 + 4x = 46

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 4x = 46 + 2

Combine like terms: -2 + 2 = 0

0 + 4x = 46 + 2

4x = 46 + 2

Combine like terms: 46 + 2 = 48

4x = 48

Divide each side by '4'.

x = 12

Simplifying

x = 12

Please help me !!! i will mark brain-list for the correct answer !!!
Shtirlitz [24]

Answer:

B

Step-by-step explanation:

So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.

Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.

Heres what we know however:

angle 1 + angle 2 = 180 degrees.

How do we know this?

Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.

Lets input that into our nice lil equation to get an answer:

7 degrees+angle 2 = 180 degrees

Now lets solve.

Subtract 7 on both sides, and your left with:

angle 2 = 173 degrees.

So the answer must be:

<u>173 degrees</u>

Hope this helps! ;)
