Answer:
63 degrees and 27 degrees
Step-by-step explanation:
Complementary angles are when two angles add to 90 degrees.
So, we can check if these pairs add up to 90 degrees.
45 + 95 = 140
38 + 42 = 80
30 + 51 = 81
63 + 27 = 90
The only pair of angles that are complementary is 63 degrees and 27 degrees.

Step-by-step explanation:
Let be  and
 and  endpoints of segment AB and
 endpoints of segment AB and  a point located 7/10 the way from A to B. Vectorially, we get this formula:
 a point located 7/10 the way from A to B. Vectorially, we get this formula:


By Linear Algebra we get the location of  :
