Question

Pls answer to this question pls
It is very urgent

Answer 1

x=70 ( alt. Int. <)
y=60 (""""""""""")
z=50(<s sum property of triangle)

Answer 2

Given : AB || CD
Angle A = 70°
Angle C = 60°

To find : Angle x, angle y, angle Z

Finding :
AB || CD and AD as transversal
Angle x = Angle A ....... (Alternate Interior angle property)
Therefore, Angle X = 70°...........(I)

Again,
AB || CD and BC as transversal
Angle y = Angle B ....... (Alternate Interior angle property)
Hence, Angle Y = 60°............(II)

Now in ∆AOB,
Angles AOB + OBA + BOA = 180°. (sum of all angles in a triangle)
Z + Y + 70° = 180°
Z + 60 + 70 = 180......(from equation II)
Z = 180 - (70 + 60)
Z = 180 - 130
Z = 50°...........(III)

So equation (I), (II) and (III) make up your answer.


Hope it'll help... :-D
