Answer:
Proved with RHS congruency rule.
Step-by-step explanation:
Given ΔEAB and ΔDCB are two right triangles. The figure has ∠BED≅ ∠BDE. Point B is the midpoint of segment AC.
We have to prove that ΔEAB ≅ ΔDCB
In ΔEAB and ΔDCB
BE=BD (∵∠BED≅ ∠BDE)
AB=BC (given B mid-point)
By RHS congruency rule which states that two right triangles are congruent if the hypotenuse and one side of triangle are respectively equal to the hypotenuse and the corresponding side of the other triangle.
Hence, By RHS rule
ΔEAB ≅ ΔDCB
Hence Proved.
a=180-117=63
b=180-81-63=36
so angle a is 63, and angle b is 36

The answer is B because the domain is the x value, and because the lines have arrows they continue forever, meaning that they contain all real numbers.
Answer:
10
Step-by-step explanation:
You use the distance formula by finding the x and y difference, and you get 8, for x value, 6 for y value, and then you use Pythagorean theorem to get 10 for AB.
