Points x and y are respectively 12m north and 5m east of point z. calculate xy

13

Step-by-step explanation:

when you sketch the question you find that the figure formed is a triangle

X

|\

| \

| \ ?

12m |. \

|\

Z. 5m Y

using Pythagorean theorem:

b^2 + h^2 = H^2

hence

5^2 + 12^2 = H^2

you square all the digits to get

25 +144 = H^2.

add 144 to 25 to get

144+25=169

hence

H^2 = 169

square root both sides

√H^2 = √169

hence H=13
