Step-by-step explanation:
Let the two numbers be 2x and 3x.
According to the question,
2x+3x=45
5x=45
x=45/5
x=9
so th required numbers are 18 and 27 as
2x=2*9=18
3x=3*9=27
Answer:
B. 18
Step-by-step explanation:
Given:
There are two chord in the circle.
These chords are divided in two segments.
Segments of 1 chord is 21 and 6.
Segments of 2 chord is x and 7.
Now by using Intersecting Chord Theorem which states,
"When two chords intersect each other inside a circle, the products of their segments are equal."
Hence from above theorem we can say that;
![x\times7=21\times6\\7x = 126\\x= \frac{126}{7}\\x=18](https://tex.z-dn.net/?f=x%5Ctimes7%3D21%5Ctimes6%5C%5C7x%20%3D%20126%5C%5Cx%3D%20%5Cfrac%7B126%7D%7B7%7D%5C%5Cx%3D18)
Hence the Value of x is 18.
