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

Answer:
Step-by-step explanation:
1. A square has four sides and all the sides have equal length.
2. Keeping this on mind, you must multply the lenght given in the problem by 4, as you can see below:
3. Therefore, the polynomial expresion that represents the perimeter of the square is .
