Dear student,

5 a) Since ABCD is a gm AB=CD   ...Opposites sides are equaland AD=BC  ...Opposites sides are equal2y+2=3x3x-2y=2     ...(i)also,Perimeter of gm=sum of sides  40=2x+2y+2+3x+2x40-2=7x+2y7x+2y=38     ...(ii)On solving (i) and (ii)3x-2y=27x+2y=38 On adding10x=40x=4and putting x=4 in (i)3×4-2y=2 -2y=2-12-2y=-10y=-10-2=5thus the value of x=4 and y=5b) Since ABCD is a gm B+C=180°  ...sum of angle on same side of transversaly+15°+x+40°=180°x+y=180°-55°x+y=125°     ....(i)and A+B=180°  ...sum of angle on same side of transversal3x-20+y+15=180°3x+y=180°+53x+y=185°     ....(ii)Solving (i) and (ii)x+y=125° 3x+y=185°-   -      --2x=-60°x=30°put x=30° in (i)we get, 30°+y=125°y=125°-30°y=95°thus the value of x=30° and y=95°c) Applying the property of diagonal of rhombus i.e, Diagonal bisects the opp. angle of rhombus and opp. angles of rhombus are equalA=C=60° and D=BA+B+C + D=360°60+60+B + D=360°B+ D=360°-120°B + D=240°2B=240°B=240°2=120°therefore, B=D=120°since  Diagonal bisects the opp. angle of rhombus ADB=CDB=1202=60°Similaly, ABD=CBD=60°Since all angles of ABD is 60°  its an equilateral hence, AB=BD=AD4x-4=3x+2=y-1        I             II            III    Solving I and II4x-4=3x+24x-3x=2+4x=6Now putting the value of x=6 and soving II and III3×6+2=y-118+2=y-1y=20+1y=21thus the value of x=6 and y=21
