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:
The water level is falling.
The initial level of water in the pool was 3,500 units
The water was 2,600 units high after 4 hours.
Step-by-step explanation:
The given function that models the water level is
where represents time in hours.
The function represents a straight line that has slope
Since the slope is negative, it means the water level is falling.
The initial level of water in the pool can found when we put into the function.
, hence the initial level is 3,500.
To determine the level of water in the pool after 14 hours, we put into the equation to get;
To determine the water level after 4 hours we put
