Answer:
159.37 cm^3
Step-by-step explanation:
A=lw+l(w
/2)^2+h^2+w*(l
/2)^2+h^2=9·6+9·(6
/2)^2+6^2+6·(9
/2)^2+62≈159.37384cm^3
Can you structure your question in a way that's more clear so i answer it for you?
Using the Law of Sines (sina/A=sinb/B=sincC for any triangle)
sinc/28=sin90/53 (sin90=1) multiply both sides by 28
sinc=28/53 take the inverse of sin (arcsin) of both sides
c=arcsin(28/53)°
c≈31.89° (to nearest hundredth of a degree)
So it is obvious that they rounded to nearest tenth of a degree
c≈31.9°
