Question

tell why ∆ABC is congruence to ∆PQR. Find AC and PR.​

Answer 1

Step-by-step explanation:

in triangle ABC and triangle PQR

angle ABC = angle PQR (each 120 degree)

angle ACB = angle PQR (each 30 degree)

BC = QR (5cm)

for triangle ABC congruent to triangle PQR (by ASA congruence rule)

so AC = PR (by CPCT)

3 X - 1 = X + 5 (valves of ac and pr)

3x - X = 5+1

2x = 6

x = 6/2

x = 3

therefore AC = 3x -1

= 3(3)-1

= 9-1

8cm

AND. PR= x+5

3+5

8cm
