Question

3. Find the value of x,y and z
110
a. x=110°.y=70°,z=80°b. x=70°,y=110°,z=60°
c. x=70°y=100°,z=70ºd. x=70°y=110°,z=70°​

Answer 1

X+110°= 180°(straight angle ) ( angle sum property )

x = 180-110

x = 70°

y= 110° ( alternate angles are equal )

y+z =180°(angle sum property)

110°+z = 180°

z= 180-110°

z= 70°

option d is correct

Answer 2

Answer:

d.

Explanation:

y = 110° ---- ( vertically opposite angles)

x = 70° ------ ( linear pair )

z = 70 ° ------( V.O.Angles )
