Answer:

Step-by-step explanation:
The measure of arc which the right triange cuts from the circle is  this means the central angle has the same measure.
 this means the central angle has the same measure. 
Angle with measure  is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence
 is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

Angles with measures  and
 and  are complementary angles (add up to 90°), so
 are complementary angles (add up to 90°), so
