We have a formula for that( according to the Intersecting chords theorem)

3×4=2×jk
6=jk
Answer:
y=45
x=9
z= 9 root 2
Step-by-step explanation:
This is a right isosceles triangle, so
y=45
x=9
z= 9 root 2
9²+9²=z²
81+81=z²
162=z²
√162=z
z=9√2
X=10 and y=5 so it's the first option
Answer:
66
Step-by-step explanation:
10% of 330 = 33
another 10% of 330 = 33
