Answer:
Step-by-step explanation:
The supplement of the exterior angle is 180 - 75 = 105
In a cyclic quadrilateral (a four sides figure where all the vertices touch the circumference of a circle), the opposite angles are supplementary. Therefore <a = 180 - 105 = 75
But I think you already knew that.
The question given above will require a good understanding of surd operation in order to arrive at the best answer

To solve this problem, we shall simply rationalise the denominator. This can be obtained as illustrated below:

Therefore, from the calculations made above, the solution to the question is 7√2
