Question

find the value of x.
(there is a quadrilateral with angles 68°, 108°, 134°, and x°)
x = input box

Explanation:

Step1: Use quadrilateral angle sum formula

Sum of angles in quadrilateral = $360^\circ$
Equation: $68 + 134 + 108 + x = 360$

Step2: Calculate sum of known angles

$68 + 134 + 108 = 310$

Step3: Solve for x

$x = 360 - 310 = 50$

Answer:

50
