Question

From the figure, Find (x).

• A. 16 units
• B. 20 units
• C. 10 units
• D. 5 units

Answer 1

The correct option is B

20 units

We can see that $△ABC\sim △PQR$ by AAA Similarity Criterion

$\Rightarrow \frac{AB}{PQ}=\frac{AC}{PR}$

$\Rightarrow \frac{10}{x}=\frac{5}{10}$

Thus x = 20 units
