I believe the matching would be as follows;
1. ABCD is a rhombus -Given
2. Triangle ADB congruent to Triangle CDB- Diagonals of parallelogram make congruent triangles. The two triangles share a diagonal BD as their third side.
3. ∠1=∠2, ∠3=∠4 ; CPCTE
4. DB bisects ∠ABC and ∠ADC - definition of angle bisector
Answer:
B. 9
Step-by-step explanation:
We know that a full circle should equal 360°, that'll help!
Since the 140°+3x+13 should equal to 180, because that makes the half of the circle it covers, we know how to set up our equation!
It should look like this:
3x+13=40
ISOLATE YOUR VARIABLE:
- Subtract 13 from both sides
NEXT, CONTINUE ISOLATING:
3x=27
- Divide by 3 from both sides.
FINALLY:
You will get X=9!

Answer: 0.0014
Step-by-step explanation:
Given : Number of entries in horse race = 13
Number of horses owned = 4
We assume that there are no ties .
Then , the probability that those four horses finish first, second ,third ,and fourth is given by :-
Hence, the required probability = 0.0014
