Question

For the following right triangle 7, 9,x. find the side length x

Answer 1

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

`A^(2)+B^(2)=C^(2)`

Substitute the value of A,B in the above theorem we get

`9^(2)+7^(2)=C^(2)`

`81+49=C^(2)`

`130=C^(2)`

`C=√(130)`

C=11.4

Result:

Thus the side length x =11.40
