Answer 1

∠BFA = 75º

Explanation:

First, let's add the three angle degrees provided.

`30+45+60 = 135`

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.

`(225)/(3) = 75`

∠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 :)
