Answer:
After 30 minutes
Step-by-step explanation:
Birds pop out at:
6, 12, 18, 24, 30, 36, 42, 49, 54, 60 mins respectively [6 mins interval]
Also
Dancers pop out at:
15, 30, 45, 60 mins respectively [15 mins interval]
Since at birds and dancers have popped out now (let it be TIME 0), then what is the next number [in the number sequences above] where 2 of them are same??
Looking at the list, it is 30. Hence, It will happen again after 30 minutes.

Answer:
Find length opposite to 30deg
Opposite = tan(30)*42
= 24.2
Whole side = 24.2+10
Find angle of 0 + 30deg: (say x)
Tan(x) = 33.2/42
Arctan(0.79) = x
x = 38.3
The angle to find:
38.3-30:
8.3
The angle is 8.3deg.
