Step-by-step explanation:

I did 2x plus 1 is 3

Answer:

∠ A = 65°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

∠ D + ∠ B = 180°, that is

x + 148 = 180 ( subtract 148 from both sides )

x = 32

Thus

∠ A = 2x + 1 = 2(32) + 1 = 64 + 1 = 65°
