First one

Note that the diameter forms the hypotenuse of a right triangle

So x is just complementary to the 71° angle = 90 - 71 = 19°

Do you see this???

Second one

Arc GEC and Arc GFC sum to 360°

So

230 + arc GFC = 360 subtract 230 from both sides

arc GFC = 130°

And since angle GDC is a central angle intercepting this arc, it has the same measure = 130°

You are correct !!!

Last one

WC and MQ are equal chords....and equal chords in a circle intersect equal arcs

So

arc CW is congruent to arc MQ the second answer is correct
