Will give brainliest Question on picture

Step-by-step explanation:

So think of the fractions as the flagpole height / Barbara's height: h/6

Now we do the same thing with the other side of the triangle, with the length of the shadow: 25/10

Now we know that 25/10 = h/6

Cross multiply: 25h = 10 x 6

And Solve: 60 / 25 = 2.4 feet

Let me know if you need anymore help! Good Luck!!
