Answer 1

Answer:

1 B, 2 D, 3 C, 4 D, 5 A

Step-by-step explanation:

AB is the ladder in this situation

Using the previous statement and pythagorean theorem we know that AB^2=BC^2+AC^2, then when you plug in the given lengths you have AB^2=6^2+2.5^2. Solving this we get 6.5 m, which is the length of the ladder. For question 4 you do the same process but with the new number of 8 and 6 and get 10 as your answer. For 5 you do this process backwards instead of finding the ladder length you find the length from the wall so you do 9^2=6^2+AC^2. Rearranging this you get 9^2-6^2=AC^2 and when you solve you get about 6.7
