Find the value of x from the given figure.

Short Answer

Expert verified

The value of x is 13.

Step by step solution

01

Step 1. Given information.

The two adjacent sides are given making a right angle.

02

Step 2. Theorem used.

We use Pythagoras Theorem.

Pythagoras Theorem define that in a right angle triangle, the square of the hypotenuse is equal to the sum of squares of other sides.

03

Step 3. Now find the value.

Calculation:

122+52=x2144+25=x2x2=169

Taking square root we get.

x=卤169x=卤13

Since, distance is a positive quantity so we neglect negative sign.

Therefore, the value of xis 13.
