Answer:
x = 124°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum the given angles and equate to 540°
90° + 122° + 105° + 99° x = 540° , that is
416° + x = 540° ( subtract 416° from both sides )
x = 124°
