HELP ME PLEASE!!!!!! asap

Here is your answer
Using Pythagoras' theorem
we know the
Hypotenuse^2= base^2+perpendicular^2
So here,
[tex]{x}^{2}={9}^{2}+{3}^{2}[/tex]
[tex]{x}^{2}=81+9[/tex]
[tex]{x}^{2}=90[/tex]
[tex]x=\sqrt{90}[/tex]
[tex]x=3\sqrt{10}[/tex]
HOPE IT IS USEFUL
Answer:
x = 3[tex]\sqrt{10}[/tex]
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for the hypotenuse x, that is
x² = 9² + 3³ = 81 + 9 = 90
Take the square root of both sides
x = [tex]\sqrt{90}[/tex] = [tex]\sqrt{9(10)}[/tex] = 3[tex]\sqrt{10}[/tex] ← exact value
