I already solve this question first I got x=26 and x=21.8 I want to know what is the answer

katovenus [111]

Answer:

$\large\boxed{\sf x = 26}$

Step-by-step explanation:

A right angled triangle is given to us and we need to find out the value of x . We may use Pythagoras Theorem here as ,

$\longrightarrow hypotenuse^2=perpendicular ^2+base^2 \\$

Here ,

perpendicular = 24
hypotenuse = x
base = 10

On substituting the respective values , we have ;

$\longrightarrow x^2 = 24^2+10^2 \\$

Solve the square ,

$\longrightarrow x^2 = 576+100\\$

Add ,

$\longrightarrow x^2 = 676 \\$

Put squareroot on both the sides ,

$\longrightarrow x =\sqrt{676} \\$

Simplify ,

$\longrightarrow \underline{\underline{ x =26}} \\$
