Vector Algebra
Area of triangles using ratios
Grade 12
Question:
<p>Find \(\frac{\Delta_2}{\Delta}\)</p>
<p>(a) \((1-x)y(1-z)\)</p>
<p>(b) \((1-x)(1-y)z\)</p>
<p>(c) \(x(1-y)(1-z)\)</p>
<p>(d) \((1-x)yz\)</p>
Step-by-Step Solution
Key Concept: Similar to Question 9, use area ratios accounting for the position of point \(F\) on segment \(DE\) relative to triangle \(CEF\).
