Answer:
1st option
Step-by-step explanation:
the figure is a kite
the horizontal diagonal bisects the vertical diagonal , then
x = 5
The diagonals are perpendicular , so using Pythagoras' identity
x² + y² = 13²
5² + y² = 13²
25 + y² = 169 ( subtract 25 from both sides )
y² = 144 ( take square root of both sides )
y = [tex]\sqrt{144}[/tex] = 12
