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!
For one year, plan B would be recommended, because it would be cheaper.
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
The cost of plan A is given by f(x) = 50x + 199 and the cost of plan B is given by g(x) = 90x + 50
For one year, plan B would be recommended, because it would be cheaper.
