Answer: Choice B
Building A; it is around 50.34 feet taller than building B
======================================================
Explanation:
Draw two right triangles such that they both have a reference angle of 40 degrees. Since it's an angle of elevation, place the angle near the horizontal side.
Opposite each reference angle is the height of the building, which we'll call h.
The adjacent side is the horizontal distance from the person to the building.
Building A is 120 ft away so it's height is...
tan(angle) = opposite/adjacent
tan(40) = h/120
h = 120*tan(40)
h = 100.69
This value is approximate. Make sure your calculator is in degree mode.
-----------------
Repeat the same idea for building B, except the adjacent side is smaller this time.
tan(angle) = opposite/adjacent
tan(40) = h/60
h = 60*tan(40)
h = 50.35
This value is approximate.
-----------------
Now subtract the heights
100.69 - 50.35 = 50.34
This shows that building A is roughly 50.34 taller than building B.

Step-by-step explanation:
To find the area of a circle, you need to use the formula
We have , so we need to plug it into the formula.
Since we need to round to the nearest tenth, your final answer should be
Answer: y = x +2
Step-by-step explanation:
On the number line the position of point F is at point 4.
According to the statement
We have a given that the on a number line , point D is at -3, and point E is at 6. The point F lies on the ratio of to is 2 : 3.
and we have to find the F point on the number line.
Firstly,
Number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.
So, According to given information,
Point D is at -3, and point E is at 6.
Ratio of point E to F = 6*2/3
Then
Ratio of point E to F = 6*2/3
After solving it
The point F = 2*2
The point F = 4.
So, On the number line the position of point F is at point 4.

-3 + 7 = -10
Add 3 to both sides.
7 = -7
This is false, as 7 does not equal -7.
I hope this helps!
