Given: ∆dek, de = ek

ef −∠ bisector of ∠e
m∠def = 44°, dk = 16
find: kf, m∠dek,
m∠dfe

KF=8, m<DEK=88degrees, m<DFE=90 degrees

Step-by-step explanation:

Since we already know that DK is 16 you would just have to /2 to get KF=8

m<DEK=88degrees because we already know half of the angle because EF is a bisector. so 44*2=88

m<DFE=90degrees because since EF is a bisector it split it right down the middle meaning it would be equal to 90degrees.

Hope this helps! :)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

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°
