Question

What is the value of X? A: x=18 B: x=48 C: x=82 D: x=98

Answer 1

The two given angles when added together needs to equal 180 degrees ( straight line)

X + 34 + 2x + 2 = 180

Combine like terms:

3x +36 = 180

Subtract 36 from both sides:

3x = 144

Divide both sides by 3:

X = 48

The answer is B.

Answer 2

Answer:

B: x=48

Step-by-step explanation:

Notice that both equations equal a 180 degree angle.

That'll give you the equation of x+34+2x+2= 180

First, add the common variables.

(x+2x)+34+2= 180

3x+ 36= 180

Now, subtract 36 to both sides of the equation.

3x+ 36= 180

     -36   -36

3x= 144

Then, divide both sides by 3 to isolate the variable.

3x= 144

3      3

x= 48
