Answer:
x = 20
Step-by-step explanation:
x^2 - 4x - 8 = 8
x^2 - 4x - 8 + 8 = 8 + 8
x^2 - 4x = 16
x (x - 4) = 16
x - 4 = 16
x - 4 + 4 = 16 + 4
x = 20

Answer:
B.
Step-by-step explanation:
Since we know that in 30-60-90 triangle, the side corresponding to angle 90 degrees is two times the length of side corresponding to 30 degree angle. The length of side corresponding to 60 degree angle is times the length corresponding to 30 degree angle.
We can see from our given choices that the side corresponding to 30 degree angle is 5 units.
Therefore, the side lengths of a 30-60-90 triangle will be and option B is the correct choice.
