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:
x = -7/2 multiplicity 2.
Step-by-step explanation:
4x^2 + 28x + 49 = 0
(2x + 7)(2x + 7) = 0
This is a perfect square.
2x + 7 = 0, so:
x = -7/2 multiplicity 2.
Answer:
UM hello how are you im njot really gonna answer anywaysss byee
If you mean average, then it's quite simple.
Usually when you want to find the average of something, you add them up all together and divide by how many there are.
For example, the numbers:
12, 69, 35, 67, and 2.
Steps:
1.) Add them. 12 + 69 + 35 + 67 + 2 = 185
2.) 185 divided by 5.
3.) Answer: 37
