How to solve this sum​

Answer 1

Answer:

In triangle xyz Angles sum=180

Angle Z=180

LWZ triangle =180

Answer 2

Step-by-step explanation:

in triangle xyz,

45°+30°+ angle xzy = 180°

< xzy = 180° - 75°= 105°

also < lzw + 105° = 180°

apply angle sum property of triangle in triangle lzw for the <zlw

then <zlw+ <xlw = 180°
