Answer:
x=5
Step-by-step explanation:
The right angle opposite is the hypotenuse
The 30° is the opposite
SohCahToa
Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)
10×sin(30)=5

83/9 = 9.2222222
9*9 = 81
83-81 = 2
A, C, D, and E are all functions
Midpoint formula.
The midpoint formula is (x_1+x_2)/2 , (y_1+y_2)/2
This is one method. A list wasn't provided.
