A good example of opportunity cost is you can spend money and time on other things but you can not spend time reading books or the money in doing something which can help.
Opportunity takes important part in economic theory.
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
For the slope of ln:
For the slope of mn:
- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln
Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect
