<h3><u>Step-by-step explanation of Construction :-</u></h3>
<h3>Step 1 :- </h3>
Draw a line XY = 6cm with the help of Ruler .
<h3>Step 2 :- </h3>
Mark an Angle ZXY = 30° on X and Another Angle XYZ = 100° on Y ( With the help of Compass ) .
[ According to given information in Question ].
<h3>Step 3 :- </h3>
These two angles are intersect each other at a point called as Z .
Hence , A TriXYZ is formed as shown in the constructed figure .
In which we found AngleXYZ is 50° ( By using angle sum Property of Triangle ) .
As we know , sum of all angles of a triangle is 180° .
AngZXY + AngXYZ + AngXZY = 180°.
30° + 100° + AngXZY = 180° .
AngXZY = 50°.
