Answer:
3sqrt(37) 37.5 52.5
Explanation:
To solve for b, you have to use the Pythagorean theorem, a^2 + b^2 + c^2
14^2 + b^2 = 23^2
196 + b^2 = 529
b^2 = 333
b = 3sqrt(37)
Now you can use trig to solve for the angles
sin(B) = 14/23
B = arcsin(14/23)
B = 37.5
cos(A) = 14/23
A = arcos (14/23)
A = 52.5
