For each triangle shown below, determine whether you would use the Law of Sines or Law of Cosines to find angle x, and explain how you know which Law to use. Then find angle x to the nearest tenth. NOTE: The perimeter of ABC-31

Given:

The figure of a triangle.

The perimeter of the triangle ABC is 31.

To find:

The value of x in the given triangle.

Solution:

Three sides of the triangle ABC are AB, BC, AC are their measures are respectively.

The perimeter of the triangle ABC is 31.

Subtract 7 from both sides.

Now, the measures of the sides are:

And,

Using the law of cosines, we get

Using calculator, we get

Therefore, the value of x is 37.0 degrees.

a is the right answer

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
