Cos(arcsin(0.5)) = 0.866

Use the inverse button on your calculator in degree mode for this. Inverse sin of .5 gives you an x value of 30 (30 degree angle, that is). Now find the cos(30) and round. cos(30) = .866

If B is the midpoint of line AC, AC = CD, AB = 3x+4, AC=11x-17, and CE = 49, find DE. (Show work)

larisa [96]

Answer:

2(3x+4) = 11x-17

6x+8 = 11x-17

25=-5x

x=-5

11x-17

55-17

AC = 38

CD = 38

49-38 = 11

DE = 11

Let me know if this helps!
