Can anyone help me with this I really need help this is worth 40% percent of my grade

3.00

Step-by-step explanation:

let us look at triangle BAD first. Since it give us a complete information. using the formula

sin 0 = opposite / hypotenuse

sin 0 = 2.8/5.5

sin 0 =0.5091

transfer the sin to the other side

angle 0 = 30.6 ° (angle BAD)

it is given angle DAC = angle BAD

so angle DAC also =30.6°

since CD is an opposite than we use the previous formula back

sin 0 = opposite / hypotenuse

sin 30.6 = CD / 5.8

CD = 2.95 or 3.00

i believe that the answer is

b. y-1=-2(x-4)

hope this !

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
