We will solve using the law of sines as follows:

Now, we solve for X:
![\Rightarrow X=\frac{\sin(60)}{\sin(30)}\Rightarrow X=\sqrt[]{3}](https://tex.z-dn.net/?f=%5CRightarrow%20X%3D%5Cfrac%7B%5Csin%2860%29%7D%7B%5Csin%2830%29%7D%5CRightarrow%20X%3D%5Csqrt%5B%5D%7B3%7D)
So, the length of X is sqrt(3).
Total = x^2, small square 3^2
Shaded area = x^2-9 = (x+3)*(x-3), clear? :)
Answer:
y = -2x + 2
Step-by-step explanation:
(-4-8)/(3-(-3)) = -12/6 = -2
-4 = -2(3) + b
-4 = -6 + b
b = 2
Answer:
AC = 8.3
Step-by-step explanation:
A² + 11² = 13.8²
A² + 121 = 190.44
Subtract 121 from both sides
A² = 69.44
√A = √69.44
AC = 8.3
I am pretty sure a is the correct answer
