Consider kite FGHJ. What are the values of a and b?

Answer:
Hmmm... interesting on my final I answered B: a=14, b=8 and got it wrong but, when I did it again I got C: a=17, b=6
Step-by-step explanation
Answer:
The value of a=17 cm and b=6 cm
C is correct option.
Step-by-step explanation:
Given: FGHJ is a kite.
Kite has property their adjacent sides are equal. Top two side of the kite is equal and bottom two side of the kite is equal.
FG=GH because ∠F=∠H.
30=2a-4
2a=34
a=17 cm
Similarly, ∠F=∠H
FJ=HJ
3b+6=24
3b=18
b=6 cm
Hence, The value of a=17 cm and b=6 cm
