Answer 2

Answer:

x = 3 yd

Step-by-step explanation:

We know the triangle is a right angle due to the symbol, so we can use pythagoras theorem to find the missing side:

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

Changing the subject to a/b as we have the hypotenuse but not a side:

$b^2 = c^2 - a^2$

Substitute in the known variables:

$b^2 = 5^2 - 4^2$

$b^2 = 25 - 16$

$b^2 = 9$

Square root both sides:

$\sqrt{x^2} = \sqrt{9}$

$x = \sqrt{9}$

x = 3 yd

Hope this helps!
