Its A.
because if the base is 13 and 13 and the sides are 10 cm multiply and get A.

Step-by-step explanation:
Answer:
It is BFA
Step-by-step explanation:
An inscribed angle stays inside the circle. If you go through each angle options, the other angles go out of the circle. BFA is the only angle that stays inside the circle.
The angle of elevation from the hiker to the park ranger is the same as the angle of depression from the ranger to the hiker, 29°.
The tangent function of an angle is the ratio of the opposite side (500') to the adjacent side (x) in the right triangle shown. That is
tan(29°) = 500' / x
Multiplying the equation by x/tan(29°) gives
x = 500' / tan(29°)
x ≈ 500' / 0.5543
x ≈ 902 ft
f(x) = 5x^2 - 4x
g(x) = 5x + 1
Therefore f - g = 5x^2 - 4x - (5x + 1)
= 5x^2 - 4x - 5x -1
= 5x^2 -9x - 1
Hope it helps :)
