Answer:
The height of the tree = 25 feet
Step-by-step explanation:
From the given diagram : EF = 5 feet, FA = 8 feet, CA = 40 feet
∠AFE = 90° and ∠ACB = 90°
To find : CB, the height of the tree.
Solution : In ΔAEF and ΔAB C
∠AFE = ∠ACB = 90°
∠A is common angle.
So, By AA postulate of similarity of triangle, ΔAEF ~ ΔABC
Now, sides of similar triangles are proportional to each other
Hence, The height of the tree = 25 feet
Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when then:
Answer:9/16
Step-by-step explanation:
Since we know it's 3/4 use
r=(3/4)² .... =
