Answer:
Step-by-step explanation:
In order to find the value of ∠EFB here, we have to note our angle relationships.
We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.
Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.
Hope this helped!

Answer:
Step-by-step explanation:
A four sided dice 4 different faces which provide 4 different outcomes
So total number of cases in this case will be 4
Now, it is given that it is in the shape of a pyramid
Thus the base will have almost negligible chance of coming
thus let 3 sides be the sides which can come up
Thus probability of these 3 sides coming will be 1/3
Thus the probability of any 3 numbers showing except for the number on the base will be 1/3
