Hello,

When you have an inscribed quadrilateral, the opposite angles add up to 180 degrees.

So we can start with angles B and D, and write the equation x + 116 = 180.
Solving that gives us that x = 64.

Now, input 64 for x in the expression for angle A.
2(64) - 40
128 - 40
88

Angle A is 88 degrees.

Good luck,
