The answer is 36. The ruler and tree are measured at the same time, so the scaling is the same. You divide 12 by 8, which is 1.5. Since the height of the pine tree is what you are trying to find, you must multiply 24(the length of the shadow) times 1.5, which is how you get 36. :)
Answer:
15=a
Step-by-step explanation:
how I got this is because a triangle is equal to 180 so you have to add all of the things together then you get 12a=180 the reason why I got this is because if you add it so 6x+3a-1+3a+1 so you add common terms then you will equal to 12a then you divide it on both sides so then you equal to 15
You would use 6 = (0.08)w
