Answer:
KM = 15
Step-by-step explanation:
From the diagram, ΔJKL and ΔJKM are similar to each other because they share the same angle J and they are both right angle triangle. Therefore they are similar by AA property.
Since JL=25 and JM=5, JM = JL + JM= 25 + 5 = 30
Since ΔJKL and ΔJKM are similar to each other, therefore:
This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram
Answer:
45 square inches
Step-by-step explanation:
From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =
Total Surface Area of the Square pyramid = 2bs + b²
Where s = Height of the square pyramid
b = Edge length of the square pyramid
From the attached diagram, we can see that:
s = 6 inches
b = 3 inches
Total Surface Area of the Square pyramid = 2bs + b²
= 2 × 3 × 6 + 3²
= 36 + 9
= 45 square inches.
Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches
