Question

in the the fig, the measure of x is ?​

Answer 1

Answer:

40 degrees

Step-by-step explanation:

In triangle AOC,

45 + 85 + AOC = 180

130 + AOC = 180

AOC = 50

Now, angle BOD = AOC = 50 (Vertically Opposite angles)

In triangle BOD,

x + 50 + 90 = 180

x + 140 = 180

x = 180 - 140 = 40
