Given:
Triangle LJK.
LJ = 89 in, LK = 28 in and m∠L = 42°
To find:
The length of missing side JK.
Solution:
LJ = k = 89
LK = j = 28
JK = l = ?
Using law of cosine:
Substitute the given values.
Taking square root on both sides.
The length of the missing side is 70.7 in.
Option C: is the possible expressions for length, width and height of the prism.
Explanation:
The volume of the rectangular prism is
To determine the length, width and height of the rectangular prism, let us factor the expression.
Thus, factoring 5x from the expression, we have,
Let us break the expression into two groups, we get,
Factoring 4x from the term , we get,
Similarly, factoring 7x from the term , we get,
Now, let us factor out , we get,
Hence, the possible expressions for length, width and height of the prism is
Therefore, Option C is the correct answer.
