Question

Pls answer the 7th question

Answer 1

Step-by-step explanation:

as PQ||AB ∆ABC ~ ∆PQC

$\frac{pc}{ac} = \frac{pq}{ab} \\ \frac{2x}{4 + 2x} = \frac{4}{7} \\ 4(4 + 2x) = 7 \times 2x \\ 16 + 8x = 14x \\ 14x - 8x = 16 \\ 6x = 16 \\ x = \frac{16}{6} \\ x = 2.66$

pc = 2x = 2 × 2.66 = 5.32 cm

hope you get your answer
