John (whose line of sight is 6 feet above horizontal) is trying to estimate the height of a tall oak tree. he first measures the angle of elevation from where he is standing as 35 degrees. he walks 30 feet closer to the tree and finds that the angle of elevation has increased by 12 degrees. find the height of the tree.

draw the diagram if you can, because i can't visualize it

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
