Answer:
NOTES
Step-by-step explanation:
sin x= opposite / hypotenuse.
opposite=4
hypotenuse=5
sin x=4/5
x=arc sin (4/5)=53.13º
Answer: x=53.13º
The area of the actual castle would be 388,800 sq. ft.
We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.
So...
180 x 4 = 720
180 x 3 = 540
If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.
720 x 540 = 388,800
Hope this helped! :D
