Answer:</h2><h2>
The kite is 186.75 metres from the ground</h2>
Step-by-step explanation:
The length of the string, hypotenuse = 225 m
Angle of elevation, θ = 56°
Sine of an angle is the ratio of the opposite side over the hypotenuese.
Sin θ =
substitute the values in the formula,
Sin 56° =
h = 225 (Sin 56°)
= 225 (0.83)
= 186.75 metres
The kite is 186.75 metres from the ground
Let
be a set of orthogonal vectors. By definition of orthogonality, any pairwise dot product between distinct vectors must be zero, i.e.
Suppose there is some linear combination of the
such that it's equivalent to the zero vector. In other words, assume they are linearly dependent and that there exist
(not all zero) such that
(This is our hypothesis)
Take the dot product of both sides with any vector from the set:
By orthogonality of the vectors, this reduces to
Since none of the
are zero vectors (presumably), this means
. This is true for all
, which means only
will allow such a linear combination to be equivalent to the zero vector, which contradicts the hypothesis and hence the set of vectors must be linearly independent.
