Answer:
2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.
3)
as it is given in the question.
4)
is the reflexive property.
5) ΔSHD ≅ ΔSTD by RHS congruency.
Step-by-step explanation:
Given in the question:

In ΔSHD and ΔSTD
(Given)
(SD ⊥ HT)
(Common)
Therefore,
(By RHS rule)
Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is 
Answer:
Step-by-step explanation:
We are given:
2
- ----------
-13
Since a negative number (-2) divided by another negative number results in a positive number,
2
----------
13
Both Answers A and B are correct; the final value in each case is +2/13.
I think it’s B if not I can’t tell because I can’t see all the questions .
