Answer:

Step-by-step explanation:

SPQ = 43˚ because the angle between a tangent and a chord is equal to the angle in the alternate segment.

SOQ = 86˚ because the angle subtended by an arc at the centre is twice the angle subtended at the circumference.

SQ is not a diameter, if it was SOQ would need to be 90˚(angle at a semicircle)
