Atriangle has one angle measuring 3x degrees the second angle measures 2x +20° and the third angle measures 4x -20° what is the value of x

Step-by-step explanation:

We have been a triangle has one angle measuring degrees the second angle measures degrees and the third angle measures degrees. We are asked to find the value of x.

We know that all interior angles of a triangle add up-to 180 degrees.

Combine like terms:

Divide both sides by 9:

Therefore, the value of x is 20 for our given triangle.

$79500

step-by-step explanation:

7.25

step-by-step explanation:
