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:
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:
[tex]a^2 + b^2 = c^2[/tex]
As we have both sides, we can calculate x by plugging the values in:
[tex]12^2 + 5^2 = x^2[/tex]
144 + 25 = [tex]x^2[/tex]
169 = x²
Square root both sides to find x:
[tex]\sqrt{169} = \sqrt{x^2}[/tex]
x = 13
Hope this helps!
