Question

Answer Math Chapter 3 Understanding quadrilaterals

Answer 1

Answer:

y = 40

x = 110

z = 30

i hope u got it.

Answer 2

EXPLANATION:-

∠ABC+70=180  [linear pair]

∠ABC=180-70

∠ABC=10

NOW,

∠ABC=x   [Opposite angles of parallelogram are equal]

x=110

NOW,

40+110+∠DCA=180  [ASP OF TRIANGLE]

∠DCA=30  

NOW.

40=y    [Vertical opposite angle]

y=40

NOW,

∠DCA=z  [VERTICAL OPPOSITE ANGLE]  

z=30

Hence x=110 ,y=40,z=30
