For two adjacent angles with measure x and ( x + 30 ) that makes up a 90 angle what is x?

20

30

60

15

1 answer

To find the value of \( x \), we can set up the equation based on the information provided.

The two angles are \( x \) and \( x + 30 \), and they add up to make a right angle (90 degrees). Therefore, we can write the equation:

\[ x + (x + 30) = 90 \]

Now, simplify the equation:

\[ 2x + 30 = 90 \]

Next, subtract 30 from both sides:

\[ 2x = 60 \]

Now, divide both sides by 2:

\[ x = 30 \]

Thus, the value of \( x \) is 30.
