Question

Someone please help me answer this

Answer 1

The given triangle is a Right angled triangle

So, by applying Pythagoras theorem :

here's the solution,

=》

$13 {}^{2} = b {}^{2} + 5 {}^{2}$

=》

${b}^{2} = 13 {}^{2} - {5}^{2}$

=》

${b}^{2} = 169 - 25$

=》

${b}^{2} = 144$

=》

$b = \sqrt{144}$

=》

$b = 12$

value of b = 12 yards
