From trig text. Am supposed to find complementary angles $a$ and $a^2$. Tried completing the square, got
$(a + 1/2)^2 = 361/4$.
Stuck. Help.

Hint: Take the square root of both sides, in the equation you got after completing the square.
As columbus8myhw noted, remember to put a $\pm$ sign.
Note that $19^2=361$
