Here is your solution for the problem.
Thanks
In a 45 45 90 triangle the sides are x by x by x*sqrt(2) respectively
therefore x*sqrt(2) = 2 [the 2 that was mentioned in the question]
solving for x
x = 2 / sqrt(2) = sqrt(2) [after rationalizing the denominator]
x = sqrt(2) is now our side length
Area of Square = (side length)^2
so the Area of this Square = (sqrt(2))^2 = 2
therefore your answer is 2
For this case we have to:
The circumference or perimeter of a circle is given by:
where d is the diameter of the circle.
Substituting the given value of c, , we have:
Therefore, the diameter of the circle is 6m.
Answer:
Option C
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
It will be 18 spoonfuls because you have to do 6 times 3 which is 18.
