In isosceles AABC, AC is the base. Points D, E, and
Fare the midpoints of AB, AC, and BC,
respectively. The length of BD is 13 inches and
mZBFD = 65°. Find each measure.
a. AB?
b. DE = 2
C. AD -
d. mŁEDF = ?

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

your answer   is c
