If p → q is true, then ~ q → ~ p is __________ false.
1 answer:
If p → q <span>is true, then ~ q → ~ p is NOT false (thus true)
In essence, </span> p → q is a conditional statement whose contrapositive is, ~ q → ~ p. As you can see in the tables I attached, as long as the conditional statement is true then its contrapositive is also true which implies that a conditional statement and its contrapositive are what is known as Logical Equivalents.

Answer:
The height of the building is 400√3
Step-by-step explanation:
Given:
Angle of elevation to the top of the building = 60°
Distance from the observer to the base of it = 400 ft
We have to find the height of the building.
Let the height of the building be "h" ft
Using trigonometric ratio:
⇒
So,
Considering adjacent side as 400 ft.
⇒
⇒
⇒
⇒ <em> ...tan(60) = √3</em>
⇒ ft
The height of the building is 400 Sq-rt (3) ft in terms of radical form and in decimals it is 692.8 ft.
