Complementary angles are angles that add up to 90 degrees.
Obtuse angles are greater than 90 degrees, so there's no way
to add two of them together and get a sum that's smaller than
either one already is.
The answer to the question is 'No'.
The first one is 5c√10c/3d^3
The answer is: A, 5c√10c/3d^3
Hope this helps! :)
Rise over run is 7 over 2 so 7/2 is the slope
