Step-by-step explanation:
From the figure attached,
In the given right triangles ΔADB and ΔCDB,
Statements Reasons
1). ∠BAD ≅ ∠BCD 1). Given
2). BD ≅ BD 2). Reflexive property
3). ΔADB ≅ ΔCDB 3). By LA theorem of congruence of right triangles
Therefore, there is sufficient information to prove the ΔADB and ΔCDB congruent.
Leg-angle theorem (L-A) will be used to prove the right triangles congruent.

The answer to your question is (x - 4)² + (y - 5)² = 100
Step-by-step explanation:
Data
Point = (-2, -3)
Midpoint = (4, 5)
Process
1.- Find the length of the radius using the formula of the distance between two points.
dPM =![\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}](/tpl/images/0590/8955/3e2e4.png)
x1 = -2 y1 = -3 x2 = 4 y2 = 5
dPM =![\sqrt{(4 + 2)^{2} + (5 + 3)^{2}}](/tpl/images/0590/8955/39415.png)
dPM =![\sqrt{(6)^{2} + (8)^{2}}](/tpl/images/0590/8955/f47a4.png)
dPM =![\sqrt{36 + 64}](/tpl/images/0590/8955/12763.png)
dPM =![\sqrt{100}](/tpl/images/0590/8955/bf0a4.png)
dPM = 10
2.- Find the equation of the line
(x - h)² + (y - k)² = r²
h = 4
k = 5
r = 10
(x - 4)² + (y - 5)² = 10²
(x - 4)² + (y - 5)² = 100
