Question

In the figure below, lines that appear to be tangent are tangent. Point O is the center of the circle. Which is the value of x? (The angle given is 43 degrees)

-43
-47
-90
-136

Answer 1

it’s B which is 47 degrees

Answer 2

The value of x would be 47 degrees.

If the line is truly tangent, then the angle that is formed there is 90 degrees.
Since every triangle is 180 degrees, we just need to subtract the two known angles to find the value of the 3rd angle.

180 - 90 - 43 = 47
