Answer:
In order to find out the tangent value of 45 degrees, we need to divide the opposite side to the angle by the adjacent side. Since both the opposite and adjacent sides of this triangle are the same, we can see that tan(45) is equal to 1.
Step-by-step explanation:
1/1 and 5/5 hope this helps! Pls mark as brainliest answer!!!!! :)
Answer:
a force of 1250lb is exerted
Step-by-step explanation:
since the force of the wind varies jointly as the area of the surface and the square of the velocity,
let f = force
a = area
velocity =v
from the above statement, we find out that
----1
that is
-----2
where k is a coefficent of proportionality
since velocity of wind in mph,v =50
and force in lb = 20
and surface area =
from eqn 2
we have that

making k subject of the formula
we have that

that means that
---3
however, when velocity = 125mph
surface area =
putting values in eqn 3 we have
hence a force of 1250lb is exerted
