Question

If Triangle ABC - triangleAPQR and if BC = 2.4 cm, QR = 3.6 cm, PR = 6 cm, then AC =

Answer 1

Answer:

4cm

Step-by-step explanation:

Given ,BC = 2.4cm , QR = 3.6cm&PR= 6

since ,∆ ABC ~ PQR

Ar ABC/Ar PQR=BC^2/QR^2=5.76/12.96

= 576/1296

ratio of areas= square of the ratio of their congruent sides

576/1296 = AC^2/PR^2 = AC^2/36

AC^2 = 36×576/1296 => AC = 6 × 24/36

= 4 cm

hence, AC = 4cm

Answer 2

Step-by-step explanation:

If Triangle ABC - triangleAPQR and if BC = 2.4 cm, QR = 3.6 cm, PR = 6 cm, then AC =
