The soil on the valley floor because it would not have runoff. Hope this helps.
Answer: D
They can only change one variable at a time, either water or light, not both. They could test the response to water first and follow that with an experiment for the plant's response to light. They cannot test for both at the same time.
Explanation:
for sin we divide the opposite by the hypotenuse
and for cos we require the adjacent divided by hypotenuse
we can get it through
a²+ b²=c²
ur unknown in this case is the adjustment which you can either substitute with a or b
a² + 3²=5²
a²=5²-3²
a²= 25-9
a²= 16

a=4
so that now we have found that I just sent we can find the cos of A
cos A= ⅘
