Question

Figure A is a scale image of Figure B. What is the value of x?

Answer 1

The value of x is 30

Explanation:

Step 1: Find the scale factor

`(FA)/(F B) =(45)/(27)`

Step 2: Use the scale factor to solve for x

`(45)/(27) =(x)/(18)`

`(45)(18) = 27x`

`810 = 27x`

`x = 30`

Therefore x = 30

Answer 2

x=30

Explanation:

to find the value of x you have to find K(constant number).

`(x)/(45)=(18)/(27)\\(x)/(45)=(2)/(3)\\ 3(x)=45*2\\3x=90\\x=(90)/(3)\\ x=30`
