of course, you can always use (x-1)(x-1)(2x+1)(x²-4x+5) as well.
In the diagram below, if AB = 25, AC = 15, and BD = 5, then find the length of DC.
1 answer:
The length of DC based on the information given about the triangle is 19.37.
<h3>How to calculate the length?</h3>Based on the given information, it should be noted that:
AB² = AD² + BD²
25² = AD² + 5²
625 = AD² + 25
AD² = 625 - 25
AD² = 600
AD = √600
AD = 24.5
DC² = AD² + - AB² (Pythagoras theorem)
DC² = 24.5² + 15²
DC² = 375.25
DC = 19.37
