Step-by-step explanation:
Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.
From the diagram, it appears as if . To determine if this is the case, we can find the slopes of both segments.
Since these slopes are negative reciprocals, we know that they are perpendicular.
This means we can use the formula , where b is the base (XY) and h is the height (XZ).
- Note these are interchangeable.
Using the distance formula,
This means the area is
Solving:
Delete the first parentheses by the distributive property, with the distributive property, we multiply the '3' first, then resolve it and the second parentheses eliminate by changing the sign:
<span>Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.
