Answer:
WX = 7.9
Step-by-step explanation:
By applying tangent rule (law of tan) in the given right triangle WXY.
tan(W) =
tan(27)° =
0.509525 =
WX =
WX = 7.85
WX ≈ 7.9
Therefore, length of side WX is 7.9 units.
Answer:
It would take approximately 8.82 sec for a penny to strike the person.
Step-by-step explanation:
Given:
Height of the building = 1250 feet
Height of the person = 6 feet.
Modeled equation is
We need to find the time required 't' for the penny to strike the person.
Solution:
to find the time required 't' for the penny to strike the person we will substitute;
h ⇒ height of the person.
So we get;
Now Combining the like terms we get;
Dividing both side by 16 using division property we get;
Now taking square root on both side we get;
Hence It would take approximately 8.82 sec for a penny to strike the person.
