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:
Given:-
To find:-
The simplified form.
At first we take conjucate and multiply below and above.
The conjucate is,
So now we multiply. we get,
Now we simplify. so we get,
We know the value of,
Substituting the value -1. we get,
So now we split the term to bring it into the form a+ib. so we get,
So the required solution is,
