If you already have any two sides of a right angle then the Pythagoras theorem would help.
It goes like (Hypotenuse)² = (Side A)² + (Side B)².
If you want to know more then just text me.
Hope this helps.

Answer:
C. 5
Step-by-step explanation:
Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:

Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:

Thus the x-coordinate of point Q will be 5
The x-coordinate of Q is 5.
[x-(-1+i)][x-(-1-i)]
[(x+1)-i][(x+1)+i]
(x+1)²-i²
(x²+2x+1)+1
x²+2x+2
so the answer is 2x
