18 - 7x = -20.5
Subtract 18 from each side:
-7x = -38.5
Divide both sides by -7:
x = -38.5 / -7
x = -5.5 = 5 1/2

Answer:
x = 21
Step-by-step explanation:
Because GJ is a diameter, the angle K is a right angle (90 degrees).
Thus, 4x + 6 = 90, and 4x = 84. Thus, x = 21
64+36=c^2
100=c^2
square root both sides for 10=c
