C. The alternative form of the law of cosines
When given all three side lengths of a triangle but none of the angle measures, you can solve for all angle measures using<u> the alternative form of the law of cosines</u>.
<h3>Explanation;</h3>
- From the law of cosines, given that a, b and c are the edges of a triangle and A, B and C are the corresponding interior angles of the the triangle.
<h3>Then; a² = b² + c² − 2 bc cos A, or</h3><h3> b² = a² + c² − 2 bc cos B, or</h3><h3> c² = a² +b ² − 2 bc cos C</h3>
Therefore; when given all the sides or edges of the triangle;
- we can use the law of cosines to find one angle, then
- we use the law of cosines again to find the second angle, and finally,
- we use the point that angles in a triangle add up to 180 to get the third angle;

Answer:
K is class A and L is 40%.
Step-by-step explanation:
Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.
