Question : 17

Total: 45

In the diagram, PQ//RT, QR//Su,

Solution:

Concept:

Use properties of parallel lines and angles on a straight line.

Explanation:

Since

PQ \parallel RT

, the alternate interior angles are equal.

Thus, the angle corresponding to the given

48^\circ

is also

48^\circ

Angle

x

and this

48^\circ

angle lie on a straight line.

So,

x + 48^\circ = 180^\circ

Therefore,

x = 180^\circ - 48^\circ = 132^\circ

Answer:

x = 132^\circ

Correct option: B.

132^\circ
