a triangle had one angle measuring 3x degrees. A second angle measures 2x+20 degrees and the third agle measures 4x-20 degrees. what is the value of x?

Answer 1

The sum of the measures of the angles in a triangle is always 180 degrees.

So, we can write the equation:

3x + 2x + 20 + 4x - 20 = 180

Combine like terms:

9x = 180

Divide both sides by 9:

x = 20

Therefore, the value of x is 20.
