Answer:

x = 18

Step-by-step explanation:

sum of interior angles of a polygon is determined by the formula

(n - 2) · 180° where 'n' is the number of sides the polygon has

there are 5 sides in this problem so the number of degrees is 3 · 180 = 540°

we can get the sum of all 5 angles and set it equal to 540

3x + 23 + 9x - 6 + 7x - 4 + 90 + 95 = 540

19x + 13 + 185 = 540

19x + 198 = 540

19x = 342

x = 342/19 = 18
