Answer:
5√3
Step-by-step explanation:
The ratio of side lengths in a 30-60-90 triangle is ...
1 : √3 : 2
__
Multiplying by 5, we have ...
1 : √3 : 2 = x : y : 10 = 5 : 5√3 : 10
The value of y is 5√3.
_____
<em>Additional comment</em>
y is the side adjacent to the 30° angle, so can be found from ...
Cos = Adjacent/Hypotenuse
Adjacent = Cos × Hypotenuse . . . . . multiply by hypotenuse
y = cos(30°)×10 = (√3)/2 × 10 . . . . . . substitute corresponding values
y = 5√3
__
The value of x is 5.
Answer:
10,300.77 cm³
Step-by-step explanation:
Radius = ½(diameter)
Diagonal:
sqrt[243 + 243]
sqrt(486)
Diameter
sqrt(486 + 243)
27
Radius: 27/2
Volume of sphere:
4/3 × pi × r³
4/3 × 3.14 × (27/2)³
10300.77 cm³
Answer:
I think its agree. I hope that helped
Step-by-step explanation:
Answer:
you are correct, it is all of the above
Answer:
multiply 5 x 4 = 20
multiply the dimensions of the lighter square
after all the multiplying you subtract your answers and you should get the VERY final answer
*don't add because it's area; just multiply
