Question

9) Transversal Icuts parallel lines m/n and
o. Find all the angles marked in the
given figure​

Answer 1

Answer:

<X = <Y = <Z = 130°.

Step-by-step explanation:

As the transversal cuts three parallel lines m,n,o,

then,

<X = <Y = 130°,

Case-1 :

<(Y-80°) = <(Z-80°),

which means <Y = <Z =130°,

Case-2 :

As transversal is a straight line,

<X + <(Z-80°) = 180°,

<X + <Z = 260°,

<Z = 130°.
