Acuckoo clock has birds that pop out of their nests every 6 minutes and dancers that pop out every 15 minutes the birds and dancers have just popped out at the same time when will this happen again in the next 60 minutes? sorry caps lock and i dont feel to write again

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.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
