Your answer would be 575.
Answer:
A:
Step-by-step explanation:
Using tangent-secant theorem
AE²=(EC)(ED)
12²=(8)(8+x+10)
144=8(x+18)
144=8x+144
8x = 144-144
8x = 0
So
x = 0
Now
ED = 8+x+10
ED = 8+0+10
ED = 18
<span>All three sides of triangle X'Y'Z' must be parallel to the corresponding sides in triangle XYZ and the corresponding angles are congruent .
The dilated triangle will be similar to the original triangle, which means all angles will be the same.
</span><span>The sides of the two triangles will also be parallel. You can test this by observing the slopes:
Line XY has a slope of 2/3, moving from -4,2 and passing through -1,4.
Line X'Y' has the same slope, moving from (-6,3) to (-3,5)
You can see that this is the case for all corresponding sides' slopes. </span>
P(A U B) = P(A) + P(B) - P(A and B)
P(A | B) = P(A and B) / P(B)
