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°


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




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



cool cool cool
