x = 12
Step-by-step explanation:
The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
( cross- multiply )
3x = 36 ( divide both sides by 3 )
x = 12
Answer:Yes
Step-by-step explanation:
Given
Suppose side length of cube is a
If we dilate the cube using a scale factor of 2
Side length becomes 2a
and the surface area becomes
Surface area
Surface area
Thus surface area multiplied by a factor of 4
Now for volume
Therefore volume is multiplied by a factor of 8
Therefore the above statements make sense
