I think it's the third one too
We know that ∠E = ∠F because of the vertical angle theorem.
Using substitution we get 8x + 8 = 2x + 38
Solve for x.
8x + 8 = 2x + 38
8x = 2x = 30 <-- Subtract 8 from each side
6x = 30 <-- Subtract 2x from each side
x = 5 <-- Divide both sides by 6
So, x is equal to 5.
Answer:
2b/ab+3
Step-by-step explanation:
Tan = opp/adj
Tan A = 16/12
In the middle:
x-coordinate= {7-(-1)}/2= 4
y-coordinate= (8-2)/2= 3
So centre is (4,3)
