Answer:
x = 45°
Step-by-step explanation:
the sum of the interior angles of a figure = (number of sides - 2) * 180
the sum of the interior angles of this figure = (5 - 2) * 180 = 540°
to find the value of x:
90 + 148+ 2x + 10 + 2x + 112 = 540
2x + 2x = 540 - 90 - 148 - 10 - 112
4x = 180
x = 180/4
x = 45
