Answer:

x= 22.6

Step-by-step explanation:

This little red square means that is a right angle (90 degrees)  

x is the complementary of 67.4  (Both add to 90)

90-67.4 = 22.6

that type of corner angle is a 90° angle, so since you know the first half of the 90° angle which is 67.4 all you need to do is subtract

so you get
90 - 67.4 = 22.6
