sum of complement  angles =  a right angle = π/2
so 
measure of Φ = π/2 - π/12
measure of Φ = 6π/12 - π/12
measure of Φ = 5π/12

answer
5π/12

Answer:

sum of complement  angles =  a right angle = π/2

so  

measure of Φ = π/2 - π/12

measure of Φ = 5π/12 + π/12

measure of Φ = 6π/12

6π/12 = π/2

answer

π/2
