Answer:
x≈12.5
Step-by-step explanation:
angle a=90°,angle b=28°,side c=11
a+b+Y=180°
Using
y=62°
Using the law of sines, we calculate unknown side x
c=11, a/c=sin a°/sin y°
a=c*sin a°/sin y°
a=11*sin 90°/sin 62°=12.46
12.46≈12.5
-4, 4/3 , 10.2
Hope this is helpful

Answer:
<u>Volume of the prism formula:</u>
<u>Volume of the given prisms:</u>
- V₁ = 5*6*4 = 120
- V₂ = 2*3*10 = 60
- V₃ = 2*8*8 = 128
- V₄ = 8*3*6 = 144
The last Prism has the greatest volume
Answer:
