Answer:
H= 10
Step-by-step explanation:
Hypotenuse formula if you have the other 2 sides.

49^(3/2)
This is the same as (sqrt49)^3
7^3 = 343
Essentially, what we need to do here is prove that BE=EC, BE=CB, and.or CE=BC therefore making it isosceles. With ∠AEC=∠DEB, we know AE=DE, so EC=EB (the points go in order). Therefore, as EC=EB, BEC is isosceles (it has at least 2 equal sides).

Answer
one answer can be x = 30
Step-by-step explanation:
triangle needs to be 180 so if xy are the shortest they can be equal so z can be 120
