Any suggestions on how to solve this? thanks
1 answer:
Answer: x = 4
Step-by-step explanation:
You basically want to solve for the angle A. Do arcsin of 1/3, which is approximately 19.47 degrees. In this triangle, we are missing the adjacent and opposite, but we do have the angle luckily. Lets use SOH-CAH-TOA.
We can see here that doing sine will give us the length of the opposite
. Do sine of 19.47, then multiply by 12. I got 4

Answer: The first option.
Step-by-step explanation:
1. The formula for calculate the perimeter is:
P=2l+2w
Where l is the lenght and w is the width.
2. The first perimeter is:
3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:
Where is the first perimeter.
4. Then:
