Answer:
Step-by-step explanation:
Let suppose base is 10-Y ( Y=3 which is line opposite to Base as shown in figure). Now extend line from side Y of size 3 to Base.It will hit base at 10-Y.
Then new rectangle will be formed in which length and width will be 6 and 3 respectively. So newly formed right angle triangle perpendicular will be same of 6 value as shown in figure.
Now apply Pythagoras theorem in which base and perpendicular will be 7 and 6 respectively.
[tex]Hyp^{2} =Base^{2} +Perp^{2}[/tex]2
x^2 = [tex]7^{2} +6^{2}[/tex]
x^2 = 49+36
x^2 = 85
x = [tex]sqrt{85[/tex]
x = 9.2154
