Question

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

Answer 1

Hey there! :)

Answer:

x = 21 units.

Step-by-step explanation:

Since we know Figure A is just Figure B scaled, we can set up a proportion:

$\frac{45}{35}= \frac{27}{x}$

Cross multiply to solve for x:

45 · x = 35 · 27

45x = 945

Divide both sides by 45:

x = 21 units.
