For this case we must observe the MQP triangle.
We observe the vertex Q of the mentioned triangle.
We note that the angle is given by:
∠MQP = 56
From here, we look for the value of the sine of the angle.
We have then:
sine (∠MQP) = sine (56)
sine (∠MQP) = 0.829
Answer:
The value of sine (∠MQP) is 0.829
