What does the law of cosines reduce to when dealing with a right triangle? A. The Pythagorean theorem B. The formula for a triangle's area C. The law of sines D. The formula for a triangle's area

Answers

Answer 1

Answer: Cosine law formula is:

$a^(2) = b^(2) + c^(2) - 2*b*c*cos(A)$

where A is an angle opposite from side a.
If angle a is 90 degrees that means that cos(90) is 0 which leaves us with
$a^(2) = b^(2) + c^(2)$

This is Pythagoras theorem where a is the hypothesis and b and c are smaller sides of triangle

Answer is A)

What is the sum of the angle measures in a 22-gon?360°
2,200°
3,600°
3,960°

Answers

Answer:

Option 3rd is correct

the sum of the interior angles measures in a 22-gon is, 3600°

Step-by-step explanation:

Sum of the interior angles of a polygon of n -sides is given by:

$\tetx{Sum} = (n-2) * 180^(\circ)$ ....[1]

As per the statement:

Given that:

n = 22-gon

Substitute in [1] we have;

$\text{Sum} = (22-2) * 180^(\circ)$

⇒ $\text{Sum} = 20 * 180^(\circ)$

⇒ $\text{Sum} =3600^(\circ)$

Therefore, the sum of the interior angles measures in a 22-gon is, 3600°

The sum of the angle measures in a 22-gon is 3600° (option c).

The sum of the angle measures in an n-gon (polygon with n sides) can be calculated using the formula:

Sum of interior angles = (n - 2) * 180°

For a 22-gon, n = 22, so the sum of the interior angles is:

Sum = (22 - 2) * 180°

Sum = 20 * 180°

Sum = 3600°

Therefore, the correct answer is option C: 3,600°.
