For two adjacent angles with measures x°

Question

and (x+30)°
that make up a 90°
angle, what is x
?(1 point)

A. 60

B. 15

C. 30

D. 20

Answer 1

To find the value of \( x \), we can set up the equation based on the information given. The two angles are \( x \) degrees and \( x + 30 \) degrees, and they add up to \( 90^\circ \):

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

Now, we simplify the equation:

\[ 2x + 30 = 90 \]

Next, subtract 30 from both sides:

\[ 2x = 90 - 30 \] \[ 2x = 60 \]

Now, divide both sides by 2:

\[ x = 30 \]

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