Answer:
D is correct
Step-by-step explanation:
a straight line is 180 degrees.
Answer:
(6,9) nice
Step-by-step explanation:
The pythagroean theorem says a² + b² = c² and we're given a and c in this case
12² + b² = 13²
144 + b² = 169; subtract 144 from both sides
b² = 25; square root both sides
b = 5 so the length of side AB is C) 5
r = 1 + cos θ
r = 1 − sin θ
r ≥ 0, 0 ≤ θ < 2π
(r, θ) = (smallest r-value)
(r, θ) =
(r, θ) = (largest r-value)
