A complex number is made of two parts: one real part (without i) and one imaginary part (with i).
The conjugate of a complex number is found by inverting the sign of the imaginary part of the number.
Therefore, the conjugate of 10+3i is 10−3i
I suggest drawing a graph or simply using a calculator
The answers should be (5 - √ 41) / 2 and (5 + √ 41) / 2

The length of the arc cannot be found without knowing some linear measure of the circle. None are given.
The measure of arc AB is twice that of angle APB, so is
2*108° = 216°.
The measure of arc APB is the difference between that and 360°, so is
360° -216° = 144°.
