Answer 1

Answer:(2) A ABC is a right angled triangle. If AB = 7 cm, AC = 24 cm and 2) = = ZA = 90° find BC. Step-by-step explanation:SolutionR.E.F imageIn Δ ABC, B is at right angle.Given, AB=24cmBC=7cmusing Pythagoras theorem AB2+BC2=AC2⇒(24)2+(7)2=AC2⇒AC=(242)+(7)2=576+49=625⇒AC=25CM(i)sin A=ACBC=257cos A=ACAB=2524(ii)sin C=ACAB=2524cos c=ACBC=257
