The given matrix equation is,
.
Multiplying the matrices with the scalars, the given equation becomes,
Adding the matrices,
Matrix equality gives,
Solving the equations together,
We can see that the equations are not consistent.
There is no solution.
Answer:
Step-by-step explanation:
we know that
An <u><em>equilateral triangle</em></u> has three equal sides and three equal interior angles (each interior angle measure 60 degrees)
so
The perimeter is equal to
where
b is the length side of the equilateral triangle
we have
substitute
solve for b
Find the area
The formula of area applying the law of sines is equal to
substitute the value of b
