Answer:
option 4 = 25
Step-by-step explanation:
given= chord js and hL intersects at poimt p
to find = value of x
solution:according to the therom;
if the line extensions of the chordJS and HL INTERSECTS at point K then their lenghts satisfy
JK×KS=HK×KL
10×30=X×12
300=12x
300/12=x
25= x

Answer:
2.5
Step-by-step explanation:
From the diagram, figure B was enlarged to obtain figure A.
The two figures are therefore similar.
The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.
It is given by:
![k = \frac{image \: length}{corresponding\:object \: length}](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7Bimage%20%5C%3A%20length%7D%7Bcorresponding%5C%3Aobject%20%5C%3A%20length%7D%20)
Figure B is the image of A
![k = \frac{10}{4} = \frac{25}{10} = \frac{21.5}{8.6} = 2.5](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B10%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B25%7D%7B10%7D%20%20%3D%20%5Cfrac%7B21.5%7D%7B8.6%7D%20%3D%20%20%202.5)
Therefore the scale factor is 2.5
