Step-by-step explanation:
Answer:
30.7 km
Step-by-step explanation:
The distance between the two fires can be found using the Law of Cosines. For ΔABC in which sides 'a' and 'b' are given, along with angle C, the third side is ...
c = √(a² +b² -2ab·cos(C))
The angle measured between the two fires is ...
180° -(69° -35°) = 146°
and the distance is ...
c = √(11² +21² -2(11)(21)cos(146°)) ≈ √945.015
c ≈ 30.74
The straight-line distance between the two fires is about 30.7 km.
can you please explain it more clearly
Step-by-step explanation:
Answer:
Second option: False
Step-by-step explanation:
You need to use the following identity:

Let be "x" the lenght of the buildings's shadow.
(Lenght of building's shadow)
You can observe in the figure that:

Substitute these values into
and solve for ""x":

Therefore, the length of its shadow IS NOT 12.94 feet.
