Answer:

11) x = 11

12) x = 11

Step-by-step explanation:

11) Δ RQP and Δ RLK are similar.

Hence, the ratios of the corresponding sides of the two triangles will be constant.

So, $\frac{RK}{PR} = \frac{RL}{QR}$

⇒ $\frac{x - 4}{49} = \frac{11}{77}$

⇒ $\frac{x - 4}{49} = \frac{1}{7}$

⇒ x - 4 = 7

⇒ x = 11 (Answer)

12) Δ QRS and Δ QDC are similar.

So, $\frac{QD}{QR} = \frac{QC}{QS}$

⇒ $\frac{2x - 14}{32} = \frac{6}{24}$

⇒ 2x - 14 = 8

⇒ 2x = 22

⇒ x = 11 (Answer)
