Determine whether the stated conclusion is valid based on the given information. If not, write invalid. Explain your reasoning.
3. Given: If a number is divisible by 4, then the number is divisible by 2. 12 is divisible by four.
Conclusion: 12 is divisible by 2.
SOLUTION:
If p → q is a true statement and p is true, then q. Here, a number divisible 4 is divisible by 2 also and 12 is divisible by 4. So, 12 is divisible by 2 is a valid statement by the Law of Detachment.
ANSWER:
valid; Law of Detachment
4. Given: If Elan stays up late, he will be tired the next day. Elan is tired.
Conclusion: Elan stayed up late.
SOLUTION:
If p is true, then q is true, but q being true does not necessarily mean that p is true. Elan could be tired because he worked out. So, the statement is invalid.
ANSWER:
Invalid; Elan could be tired because he worked out.

Answer:
ow do you find arc length without the radius?
To calculate arc length without radius, you need the central angle and the sector area:
Multiply the area by 2 and divide the result by the central angle in radians.
Find the square root of this division.
Multiply this root by the central angle again to get the arc length.
The units will be the square root of the sector area angle.

Or the central angle and the chord length:
Divide the central angle in radians by 2 and perform the sin function on it.
Divide the chord length by double the result of step 1. This gives you the radius.
Multiply the radius by the central angle to get the arc length.

Answer:
The answer is 72 square inches, since there are 24 triangles, and you do 36*48/24, which equals to 72.
