D
is certainly wrong. You could extend the length of AD as far as you want and the two triangles (ABD and ACD) would still be congruent.
C
is wrong as well. The triangles might be similar, but they are more. They are congruent.
B
You don't have to prove that. It is given on the way the diagram is marked.
A
A is your answer. The two triangles are congruent by SAS
Answer:
the answer is ac line segment
U just write it in word form
Step-by-step explanation:
- 19 x + 23 x = 44
4x = 44
x = 44/ 4
x = 11
Hope it will help :)
Use the FOIL method
First, Outside, Inside, Last
(2x -5)(x + 3)
2x(x) = 2x²
2x(3) = 6x
-5(x) = -5x
-5(3) = -15
2x² + 6x - 5x - 15
simplify
2x² + 6x - 5x - 15
2x² + x - 15
2x² + x - 15 is your answer
hope this helps
