Question

MARKING AS BRAINLIEST (

Answer 1

Answer:

c=13

Step-by-step explanation:

pythagoras theorem

a^2+b^2=c^2

12^2+5^2=x^2

169=x^2

x=13

This is one of the few combination of triangle you should really memorize.

Answer 2

Answer:

x = 13 in

Step-by-step explanation:

We can tell this is another right angled triangle due to the right angle symbol, meaning to find x we can use Pythagoras theory:

$a^2 + b^2 = c^2$

As we have both sides, we can calculate x by plugging the values in:

$12^2 + 5^2 = x^2$

144 + 25 = $x^2$

169 = x²

Square root both sides to find x:

$\sqrt{169} = \sqrt{x^2}$

x = 13

Hope this helps!
