Answer:
F: 48
Step-by-step explanation:
Let x be the length of the side of the cube. RQ can be expressed as a triangle consisting of a diagonal of a face of the cube and the side length x. By the pythagorean theorem, we know that a^2+b^2=c^2. So, we can express the diagonal as x^2+x^2=c^2, giving us the value of c to be 
. Now, we can once again use the pythagorean theorem to find RQ^2=2x^2+x^2=3x^2, so RQ=
=12, so x=
. To find the area of the shaded part, we multiply the length times width which gives us 
. So, the area of the shaded face of the cube is F: 48.

branliy app is very bad and poor,
Answer:
The degree of overlap between the two distributions is moderate.
Step-by-step explanation:
Answer: So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Brainliest please if I am correct! and hope it helped.
