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.
Answer:
210 cm^2
Step-by-step explanation:
The left rectangle is 65 cm^2, the middle rectangle is 60 cm^2, the right rectangle is 25 cm^2, and the two triangles are each 30 cm^2
Answer:
Step-by-step explanation:
Total share = 4 + 5 = 9
Bc = 24
Ad = 5y-1
5 times what is 25?
5 x 5 = 25
25 - 1 = 24
Therefore Y = 5
5(5) - 1 = 24
