Answer:
last option is correct
Step-by-step explanation:
use formula of reflection over x axis .
The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.
formula :
(x , y) = (x -y)
C(-8 , -1) = C'(-8 , 1)
D(-6 , -5) = D'(-6 , 5)
E(-2 , -4) = E'(-2 , 4)

Answer: A) 5</h3>
=================================================
Explanation:
Angle B = 90 degrees, and the side opposite this is the hypotenuse AC = 10.
Angle C = 30, and the side opposite this smallest angle is AB. For now we'll call this x.
It turns out that for any 30-60-90 triangle, the hypotenuse is twice as long as the short leg. So if x is the short leg, then 2x is the hypotenuse.
Set 2x equal to the given hypotenuse 10 and solve for x
2x = 10
x = 10/2
x = 5
That makes AB = 5.
In other words, we cut the hypotenuse in half to get the length of the shorter leg.
9= 30x+48
10= No they are not
11= 27+21x
