Answer:

44 or 43

Step-by-step explanation:

Sum of angles in a circle is 360.

x + 152 + 122 = 360

x + 272 = 360

x = 360 - 272

x = 88

Divide the value of x by 2

x = 88 / 2

x = 44

223 = x


We know that inscribed angles are 1/2 the measure of the arcs. Therefore:

360 - ((122/2) + (152/2)) = x

360 - ((61) + (76)) = x

360 - (137) = x

223 = x
