All numbers are real numbers.

is irrational
Step-by-step explanation:
step 1. ABCD is an isosceles trapezoid because AD and BC are parallel, AB and CD are congruent
step 2. x = 56° (definition of an isosceles trapezoid)
step 3. x + y + z + 56 = 360 (definition of a quadrilateral)
step 4. y = z (definition of an isosceles trapezoid)
step 5. 56 + 2y + 56 = 360
step 6. 2y = 248
step 7. y = 124°, z = 124°.
Answer:

Answer:
The domain of the relation is ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
Step-by-step explanation:
we have
![[(15,65),(21,70),(18,73),(16,62)]](https://tex.z-dn.net/?f=%5B%2815%2C65%29%2C%2821%2C70%29%2C%2818%2C73%29%2C%2816%2C62%29%5D)
Remember that
The domain of the relation are the values of x
The range of the relation are the values of y
therefore
The domain is
![[(5,21,18,16]](https://tex.z-dn.net/?f=%5B%285%2C21%2C18%2C16%5D)
order them from lowest to highest -------> ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
The range is
![[65,70,73,62]](https://tex.z-dn.net/?f=%5B65%2C70%2C73%2C62%5D)
order them from lowest to highest ------->![[62,65,70,73]](https://tex.z-dn.net/?f=%5B62%2C65%2C70%2C73%5D)
