Question

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

Answer 1

Answer:

x=30

Step-by-step explanation:

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

$\frac{x}{45}=\frac{18}{27}\\\frac{x}{45}=\frac{2}{3}\\ 3(x)=45*2\\3x=90\\x=\frac{90}{3}\\ x=30$

Answer 2

Answer:

The value of x is 30

Step-by-step explanation:

Step 1: Find the scale factor

$\frac{FA}{F B} =\frac{45}{27}$

Step 2: Use the scale factor to solve for x

$\frac{45}{27} =\frac{x}{18}$

$(45)(18) = 27x$

$810 = 27x$

$x = 30$

Therefore x = 30
