Find the value of x.

agasfer [191]

Answer:

$\boxed {\boxed {\sf A. \ 18}}$

Step-by-step explanation:

The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.

Therefore, the sum of the angle measures must equal 90. We can set up an equation.

$56+(x+16)=90$

Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.

$(56+16)+x=90\\$

$72+x=90$

Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.

$72-72+x=90-72$

$x=18$

x is equal to 18 and choice A is correct.
