Answer:
Step-by-step explanation:
take 30 degree as reference angle
using cos rule
cos 30=adjacent/hypotenuse
/2=7
/y(do cross multiplication)
14
=y
14
/
=y
14=y
for x
using pythagorsa theorem
H^2=P^2+B^2
14^2=X^2+(7
)^2
196=X^2+147
196-147=X^2
49=X^2
=X
7=X
Answer:
b

Answer:
what?
Step-by-step explanation:
The answer would be choice 2 : Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.
