Question

# In figure, the sides QP and RQ of are produced to points S and T respectively. If and then

Hint:

## The correct answer is: 65°

### A line is a simple, one-dimensional shape that can go on forever in the opposing directions. A line may be vertical or horizontal. It can be drawn either top to bottom or left to right.When the ends of two rays collide at a single location, an angle is the geometry that results. They are expressed as radians or degrees (°). A 360-degree angle is the same as a whole rotation. It is symbolised by the character "∠".Here we have given the sides QP and RQ of  are produced to points S and T respectively and  and .

Here we used the concept of linear pair and angle sum property of a triangle. When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. So here the angle PRQ is 65 degrees.
