Opposite angles are equal so the equation is
x + 71 = 108 (A)
I'm not sure what the answers are, but I can help. If you go to the x axis and search for 50, then go straight up to the line of best fit, you'll find the estimated height of the tree. It appears to be about 70.
Hope this helps!
Answer:
y= -10x+200, x is equal to a week
Step-by-step explanation:
formula y=mx+b
we lose 10$ a week so the slope is -10 and we start with a base amount of 200
so plug those numbers in and you have y= -10x+200
