Answer:
The side length x=11.40
Step by Step Explanation:
Given:
Two sides of the right angled triangle=7,9
To find:
Side length x
Solution:
Let A,B,C be the sides of the right angled triangle such that
A=9, B=7 and C=?
Side length can be calculated by using Pythagorean Theorem
According to this theorem
[tex]A^{2}+B^{2}=C^{2}[/tex]
Substitute the value of A,B in the above theorem we get
[tex]9^{2}+7^{2}=C^{2}[/tex]
[tex]81+49=C^{2}[/tex]
[tex]130=C^{2}[/tex]
[tex]C=\sqrt{130}[/tex]
C=11.4
Result:
Thus the side length x =11.40
