Given that in ΔABC side AB = (3x +10)cm, ∠A = 2x +15° and in ΔPQR side QR = (5y + 15)cm, ∠R = 5x - 60°. Also ΔBAC = ΔQRP by SAS criterion of congruence.

Answer:
x=15,y=8
Step-by-step explanation:
AB=QR(given by SAS congruence)
3x+10=5y+15
3x-5y-5=0
∠A=∠R (given by SAS congruence)
2x+15°=5x-60°
3x-45°=0
x=45/3
x=15
3x-5y-5=3(15)-5y-5=0
45-5y-5=0
40-5y=0
40=5y
8=y
