Answer:
A. 5
Step-by-step explanation:
This is a kite, in which line segments DC & BC are congruent. Set the measurements equal to each other:
6x = 30
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.Divide 6 from both sides:
(6x)/6 = (30)/6
x = 30/6
x = 5
A. 5 is your answer.
