Question

find the value of x.
(image of a quadrilateral with angles 104°, 72°, 132°, and x°)
x =

Explanation:

Step1: Recall quadrilateral angle sum

The sum of interior angles of a quadrilateral is $360^\circ$.

Step2: Sum known angles

Calculate total of given angles:
$104^\circ + 72^\circ + 132^\circ = 308^\circ$

Step3: Solve for $x$

Subtract sum from $360^\circ$:
$x = 360^\circ - 308^\circ$

Answer:

$52^\circ$
