Question

sketch the proper figure and write the answers of the following questions if x - y - z and l(x,z) = 3✓7 , l(x,y) = ✓7 , then l(y,z) = ?​

Answer 1

Answer:

2√7

Step-by-step explanation:

given: x-y-z

Therefore l(x,z) = l(x,y) + l(y,z)

l(y,z) = l(x,z) - l(x,y)

l(y,z) = 3√7 - √7

l(y,z) = 2√7
