Question
In the given figure, if and then the value of is
The correct answer is:
We were given with a diagram and asked to find the angle
Draw a line AB parallel to PQ, so AB∥PQ and PQ∥RS, so AB∥RS.
It is known that the sum of two interior angles on the same side is 180, therefore,
∠QXM+∠XMB=180
∠XMB=180−135
∠XMB=45
alternate interior angles are equal, so,
∠BMY=∠MYR
∠BMY=40
Now, ∠XMY=∠XMB+∠BMY
=45+40
=85
Hence 85o is correct option
