<h3>#a</h3>
∠XBC= 55°
[ By corresponding angles]
- Corresponding angle are the angles which hold sane relative position as another angle but somewhere else on the figure.

<h3>#b</h3>
∵ XB and XC are equal, ∠XBC=∠BCX
<h3>Now, With angle sum property of triangle: </h3>

Dividing the line segment AB into ratio 1:3 or 3:1 means dividing the line segment into four equal lengths, as shown in the diagram below.
Point P is the point that divides the line into 1 part and 3 parts, from A.
Point Q is the point that divides the line into 1 part and 3 parts, from B
Hence, P and Q are points on different position
Answer:
