Okie, so percent decrease is the amount loss divided by the original number and multiplied by 100 to find the percent. This is because you are finding the amount loss in terms of the total amount - percent basically.
The amount loss : 4 feet
4 feet/ 12 feet = .3333 (ratio of how much cut) multiply by 100 --> 33.3% decrease. From 12 feet to 8 feet is a 33.3 % decrease. I hope this helps :-)

What is sin A=0.3784 rounded to the nearest whole degree
DENIUS [597]

Answer:

∠A = 22°

Step-by-step explanation:

Given:

\sin (A)=0.3784

We take inverse of sine to find angle A.

So, \angle A=sin^{-1}(0.3784)=22.23°

22.23° rounded to nearest whole degree is 22°.

∴ \angle A=22°.
