Here's a diagram showing how to combine angles LDA (in red) and angle ADE (in blue). Hopefully it becomes a bit clearer why these two angles add up to line segment LE. Erase the shared segment DA if it helps show LE better.

Answer:
y=-5x-2
Step-by-step explanation:
y=mx+b
where m is the slope
y=-5x+b
to solve for b, which is the y intercept, plug in (1,-7)
-7=-5(1)+b
-7=-5+b
-2=b
y=-5x-2
Answer:
600,000
Step-by-step explanation:
Answer:
16 feet
Step-by-step explanation:
Set up a proportion where x is the height of the tree:
= 
Cross multiply and solve for x:
5x = 80
x = 16
So, the tree is 16 feet tall
