Answer:

x = 10.6 units

Step-by-step explanation:

We can use sine to solve this since sine is opposite over hypotnuse.

sin(62) = x/12

.883 = x/12

x = .883 * 12

x = 10.6

Elena-2011 [213]
--------------------------------------------------
Define x :
--------------------------------------------------
Let Cheryl be x years old.
Cheryl = x
Lisa = x + 6

x + 8 = 2(x + 2)
x + 8 = 2x + 4
x = 4

Cheryl = x = 4
Lisa = x + 6 = 4 + 6 = 10
