Answer:
12.
Step-by-step explanation:
it takes 24 days to completely cover the whole pond.
to cover half the pond, it takes an x amount of time (x is unknown) x is equal to the half of 24. That means 24 = 2x and x=12.

<u>Answer:</u>
∠MKL
<u>Step-by-step explanation:</u>
Two angles are said to be adjacent angles if they share a common vertex and a common side but they do not overlap.
The triangle given here is ΔMKL with a line extended outside from K to J.
The two angles ∠MKL and ∠MKJ are adjacent angles as they share a common vertex K and a common side which is MK. The angle ∠MKL comes in the closed triangle while ∠MKJ is formed by extending the point K.
Therefore, ∠MKL is an interior adjacent angle while ∠MKJ is the exterior adjacent angle here.
