With DC = AB, you have a pair of sides.
Then with the parallel lines, you get angles 2 and 3 are congruent because they are alternate interior angles.
Finally, side AC is congruent to side AC. That gives you another pair of congruent sides.
You can use SAS.
Answer:
10
Step-by-step explanation:
geometric mean theorem :
h = sqrt(pq)
p, q being the segments on the Hypotenuse of the right-angled triangle.
so, x = sqrt(9×10) = 3×sqrt(10)
y = x² + 6x + 5
Use the formula: -b/2a
a = 1
b = 6
- 6 / 2
= -3
The x-coordinate of the vertex is -3
Plug the x value back into the original equation to find the y-coordinate of the vertex
y = (-3)² + 6(-3) + 5
y = -4
<h3>Answer: (-3,-4)</h3>

Answer:
True
Step-by-step explanation:
A true proportion is an equation that states that two ratios are equal. If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.
