Step-by-step explanation:
Coordinate of B = 1
Coordinate of D = 6
Coordinate of A = -1
BD = |1 - 6| = 5 units
AD = |-1 - 6| = |-7| = 7 units
Plug in the values
Answer:
∠BFA = 75º
Step-by-step explanation:
First, let's add the three angle degrees provided.
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.
∠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 :)
