The cross-section of the cube that is obtained by slicing a cube parallel to one of it's face is:
Square
<h3>Step-by-step explanation:</h3>We know that the faces of a cube are made up of squares.
As, the cube has 6 faces each made up of squares.
so, when is slicing is done parallel to any of the faces of a cube then we will obtain the slice similar to the shape of the face of the cube.
i.e. the cross-section of the slice so formed is:
Square.
Also, the slicing could be seen with the help of a figure.
Answer:
x = 25
Step-by-step explanation:
From the picture attached,
ΔABC and ΔADE are the similar triangles.
Therefore, their corresponding sides will be in the same ratio.
And AB = AD + DB
= 2(AD) [Since, AD = DB]
By substituting these values,
2 =
x - 8 =
x - 8 = 17
x = 17 + 8
x = 25
Solution given:
Cos
equating corresponding value
we get
adjacent=10
hypotenuse=17
perpendicular=x
now
by using Pythagoras law
Hypotenuse ²=perpendicular²+adjacent ²
substituting value
17²=x²+10²
17²-10²=x²
x²=17²-10²
x²=189
doing square root
x=
now
In I Quadrant sin angle is positive
Sin
