Question

If the measure of angle 4 is 3x + 20 degrees and angle 6 is 2x, what is the value of x?

x = 15
x = 30
x = 32
x = 75

Answer 1

To find the value of x, set up an equation using the given angles 4 and 6. Solve for x by combining like terms and isolating x on one side of the equation.

Step-by-step explanation:

To find the value of x, we need to set up an equation using the given angles 4 and 6.

Angle 4 = 3x + 20 degrees

Angle 6 = 2x degrees

Since angle 4 and angle 6 are the same, we can set up an equation:

3x + 20 = 2x

Subtracting 2x from both sides:

x + 20 = 0

Subtracting 20 from both sides:

x = -20
