Answer 1

`\huge\boxed{157 \ \ \text{degrees}}`

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.

`23 + x = 90\\\\x = 90-23\\\\x = 67`

Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.

`90+67=157`

Hope this helped!
