Answer:

The value of
x:


x = 20

Explanation:

-Since, one angle with the measure
x + 40 and another angle with measure
3x are vertical angles, they equal each other. So, it will be written as:


x + 40 = 3x

-After you have formed an equation, you switch the equation and you solve for the value of
x:


x + 40 = 3x


x - x + 40 = 3x -x


40 = 2x


(40)/(2) = (2x)/(2)


20 = x

So, the final answer is
20 = x or
x = 20 (They are both the same, you just switch them).

Answer:

x = 20

Explanation:

The angles are vertical angles and we know that vertical angles are equal

x+40 = 3x

Subtract x from each side

x+40-x = 3x-x

40 = 2x

Divide each side by 2

40/2 = 2x/2

20 =x
