Question

In figure, AB ║CD find the values of the angles x, y and z
respectively.
(A) 137°, 43°, 56°
(B) 122°, 56°, 48°
(C) 116°, 43°, 56°
(D) 137°, 56°, 48°

Answer 1

Here is your answer! ! ! !

Angle ABC = y ( Alternate interior angle )
So y = 43

Angle x + Angle ABC = 180 ( Angles on straight line )
Angle x + 43 = 180
Angle x = 137

Angle ABC + Angle z + ANGLE CAB = 180 ( Angle sum property )
43 + Angle z + 81 = 180
Angle z + 124 = 180
Angle z = 56


So Angle y = 43
Angle x = 137
Angle z = 56




I hope its helpfull for you.
