Marking as brainliest

Answer:
x = 12.49 yd
Step-by-step explanation:
We know that the triangle has a right angle due to the symbol so that means we can use pythagoras theorem to calculate x.
[tex]a^2 + b^2 = c^2[/tex]
However, we need to change the subject to a or b as we have the hypotenuse but not a side:
[tex]a^2 = c^2 - b^2[/tex]
Now substitute in the known variables:
[tex]16^2 - 10^2 = x^2[/tex]
[tex]256 - 100 = x^2[/tex]
[tex]156 = x^2[/tex]
Square root both sides to find x:
[tex]\sqrt{156} = \sqrt{x^2} \\x = \sqrt{156}[/tex]
x = 12.49 yd
Hope this helps!
