Tan80=5.67
2tan70+tan10=5.67
So tan80=2tan70+tan10
Set up an equation 20=k(0.4)....to find k divide 20 by 0.4
Answer:

Step-by-step explanation:

(1, 3) ⇒ x₁ = 1, y₁ = 3
(7, 2) ⇒ x₂ = 7, y₂ = 2
So the slope:

The answer is D) 3,404
By putting the table values into the progam DESMOS, and then putting in the formula, the answer will be given- and that answer is 3,404.
