Answer:
a is 31 b is 38 x is 133. Y is 47
Step-by-step explanation:
A is 31 because the other side is 31. we know the sides are the same because of the markings. B is 38 because the other side is 38 we know that because of the markings which mean its the same. X is 133 Y should be 47 because ALL ANGLES IN A QUADRILATERAL IS EQUAL TO 360. 133+133=266 360-266 is 94. 94 is for both angles so we need to divide by 2 the answer for Y is 47

That's addition of mixed numbers. Convert 3/7 and 5/9 to fractions with the denominator (7)(9) = 63 (this is the LCD):
10 27/63 + 19 35/63
This comes out to 29 62/63.
It’s 178-9 that’s the answer
