Find the value of x.l

Answers

Answer:

The value of x is 28°

Step-by-step explanation:

2x + 1 and 33° together forms 90° angle.

So, we need to find the angle at the 2x + 1.

--> 90° - 33°

= 57°

So, 2x + 1 gives 57°.

So, to find x :-

2x + 1 = 57°

2x = 57 - 1

2x = 56

x = [tex]\frac{56}{2}[/tex]

x = 28

2 - x = x - 8

ayudaaa
porfavor

Answers

Answer:

x=5

Step-by-step explanation:

2 - x = x - 8

- x = x - 8 - 2 (subtract 2 from both sides)

- x = x - 10 (combine like terms)

- 2x = - 10 (subtract x from both sides)

x = 5 (divide each side by -2).

Answer:

x = 5

Step-by-step explanation:

2 - x = x - 8

- x + 2 = x - 8

- x + 2 - 2 = x - 8 - 2

- x = x - 10

- x - x = x - x - 10

- 2x = - 10

- 2x ÷ - 2 = - 10 ÷ - 2

Step-by-step explanation:

250+2x=360

2x=110

x=55

Answer:

Step-by-step explanation:

There are many ways to solve this problem; however, I used the one I believe to be the fastest and easiest, but you can still use a different way.

I solved this by using the fact that the green angle (m<125) and the red angle (x) make a straight line. All straight lines equal 180 degrees; therefore, this line must equal 125+x=180. Then, you can subtract 125 from both sides of the equation. That leaves x=55.
