Answer:
∠BFA = 75º
Step-by-step explanation:
First, let's add the three angle degrees provided.
[tex]30+45+60 = 135[/tex]
Then, we subtract 135 from 360º, which is all the angles added together.
360º - 135º = 225
Since ∠BFC is 2xº, then we have to divide 225 by 3.
[tex]\frac{225}{3} = 75[/tex]
∠BFC is twice the amount of x, so ∠BFC is 75 * 2 = 150º
xº is 75º
To check our answer, we can add all these angles and if they add up to 360º, we are correct.
30 + 45 + 60 + 75 + 150 = 360º :)
