Answer:
tan D = or 0.545
tan F = or 1.833
Step-by-step explanation:
To find tangent is always
so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so which is or 0.545
The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so is or 1.833
This can be solved by Newton's binomial formula
Tk+1 = (n k) a∧(n-k) b∧k k+1=7 => k=6, n=11 , a=-3x and b=-2y
T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6
T7= 462 (-3x)∧5 (-2y)∧6
The correct answer is A.
Good luck!!!
