Answer:
I'm pretty sure the exponent of y is 2. so ?=2 hope this helps :D
Step-by-step explanation:
30° = m∠GFH
Since ∠EFH and ∠GFH are complementary, the sum of their measures i 90.
Let x = m∠GFH
2x = m∠EFH
m∠GFH + m∠EFH = 90
x + 2x = 90
3x = 90
x = 30° = m∠GFH
It is A
I believe its 3
2, 9 , 16 , 23 , 30 ......
