By Pythagoras Theorem,
the length of the other leg= (12^2-9^2)^1/2
hope this helps
63 i believe correct me if i’m wrong somebody. Im possibly WAY off
If the length of the ladder is x then 12/x=cos70, so x=12/cos70=35’ approx, answer c.
Answer:
The y-intercept is at (0,8), so you can graph that point. Then the slope is -3/5. So the change in y coordinate divide the change in x coordinate is always -3/5. Thus 8-y/0-x=-3/5. You can choose any value for y and x as long as 8-y=-3. And 0-x=5. The point on the graph will just be (x,y) for the values you find.
So do 21/7 to give you how much they do in a day. The answer is three so they do 3 aceres in a day.
