Isolate x by adding 8 to both sides.
3 = x/3
Then, multiply by 3 on both sides.
9 = x
To prove that this is right, you can imput 9 into the equation and it equals -5.
You have to multiply 2.5 with 3.5 to get the area.
all the other numbers are just nonsense so to find the area you just need to multiply those 2 numbers.
2.5 km×3.5 km=8.75 km²
Cosine = adjacent / hypotenuse
cosine (A) = 6 / 10
cosine (C) = 8 / 10
Since 8 / 10 equals 4 / 5 then it is
Angle C that is the answer
