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:
D. 420
The area of a triangle is
half of(base× height)
10×16= 160
160÷2=80
That is the surface area of ONE triangle.
multiply 80 by 4 to get 320
then find the surface area of the square by doing length×width to get 100
Finally add them together
320+100=420
Answer:
The slope is 2 and the y-intercept is -6
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to
where
m is unit rate or the slope of the linear equation
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have
therefore
the slope is equal to
and
