Missing side length in the given right triangle is 15units.
What is right triangle?
" Right triangle is defined as the two dimensional closed figure with sides , three vertices and three angles enclosed in it , with one of the interior angle measure equals to 90°."
Formula used
Pythagoras theorem
(Hypotenuse)²= (Opposite side)² + (adjacent side)²
According to the figure,
In the given right triangle,
Opposite side of right triangle = 9 units
Adjacent side of right triangle = 12 units
'x' represents side length of hypotenuse of right triangle
Substitute the value in the Pythagoras theorem we get,
[tex]x^{2} = 9^{2} + 12^{2}[/tex]
⇒[tex]x^{2} =81 +144[/tex]
⇒[tex]x^{2} = 225[/tex]
⇒[tex]x=\sqrt{225}[/tex]
⇒[tex]x=15[/tex] units
Hence, missing side length in the given right triangle is 15units.
