Question 995813
Two angles are complementary.
A + B = 90
 One of the angles is 13 degrees more than half the other. 
A = .5B + 13
Find the two angles. 
In the first equation, replace A with (.5B+13)
(.5B + 13) + b = 90
1.5B = 90 - 13
B = 77/1.5
B = 51{{{1/3}}} degrees
then
A = .5(51{{{1/3}}}) + 13
A = 38{{{2/3}}} degrees
